So okay, that's fine. Nasa case like I know you can hear me now. So do you recording has started. So once again, good morning everyone and welcome to analogue signal lab with you three. To get started, I'm going to share my screen and I will go through a few slides on what this course is all about and also on the structure of discourse. Okay? So I will share my screen now. Oh, yeah, we know it's not this one. I'm trying to get the right document to sharing. Just bear with me 1 second. Does not sharing very well. Just bear with me while I try to get the light document to share. There we go. I can see my screen now. Very good. Thank you. So I believe you can some ascii, so okay. That's fine. I think we can see we can Ozzie masking. Thank you. Jessica. Thank you. So my name is who I see, who cola or you can call me popular for simplicity, just call me popular does, does better. And I'm going to be the cost organiser. And I look mixed signal laboratory 31 is to have a bit of introduction to what the course is all about. Ok, so I'll be talking to you about what the course is about and what we're going to be learning in this course. To guess that edge, as you point out that you must have received some welcome message from me. I posted it on len, and that gives you a view of what your cost is. Also uploaded. Your lecture much, yes, on to learn in the lecture slides. Everything that we'll be using for this course. Also on length. How in college you to have a look, you know, maybe after this session, please have a look if you have not done so already. So what is this course all about? What is the objective? What is the aim of this course? What are we going to learn on this particular cost? So the main objective is that we're going to be working with basic analogue electronic circuits. And for that we'll be using discrete components and operational amplifiers. Now, when I say discrete components, I mean, you are going to be using things like resistors, will be using things like capacitors. And it will be using operational amplifiers, that is op-amps for shot. I believe by now you must have done some courses on of pumps. What is an op-amp? What I decoding rules of an op amp, what we use an op-amp for, and so on and so forth. You must have done that in your previous studies. Now is the time to bring all of that knowledge together to develop a subsystem using what you've learned. Because so, because in essence is a mini-project, okay? Because the necessities like Amelie put a very short period that you would do with some guidance for myself. The idea is that this cause this mini project will prepare you for when you want to do your final BH or mange project. So you, you'll have had an experience of how to design or carry out a mini put it. So what do you need to have known what sites are there? As I mentioned, you need to have someone does timing of basic electronic components or subsystems. As an example. By now you must have done something about first order field as something like I will see the task we are representing resistor MCs for capacitor. So you can have series to make a philtre. Now you should have some understanding of how that works. Here are some understanding of the potential divider network. Or if you have a voltage source, you connect two resistors in series to a voltage source. What is the potential drop across each of the two resistors? That kind of thought. So and I believe must have done that by now. And also, you need to know a little bit about operational amplifier circuits. Like an amplifier, a non-inverting amplifier, and subnets. And fourth, Can I just ask everybody to please microphone on, mute. Can you please mute yourself? Everybody? Tech. We can hear some people. Please mute your microphone please. Because we can hear some echo. Thank you very much. So that is what I expect that you should have known by now. If you think you've learned these things and perhaps you forgot seeing, now is the time to have a quick revision. You know, go back and revise simple field as simple potential divider and the basic golden rules, an operational amplifier because you will need that knowledge in discourse. Ok? I've got to say that if you have any question, please note them down. I will give you time to ask questions. And, you know, towards the end of this session, alternatively, you can type your question in the chat box there now picked up was I finished my presentation. Okay. So related outcomes there on then as well. And it's already is put up here on the slide. I've mentioned we're using DC components and op-amps to implement analogue subsystems for a sample, we're going to be building. Passive philtres. And you will be building active fields as well and multi-stage amplifiers. On this course, Russ, important, it will be designed in a very simple trans impedance amplifier that is equivalent to a voltage amplifier in this course as well. And in doing that, you want to, in a way, balance maybe two requirements. One is the gain of your design. And what I want is the one which does the tradeoff day. If you are high-gain half blue bandwidth. And then you need to get a good balance to meet eluting specification that will retain specification is part of your beef, part of what you'll be asked to do in this course, okay? And once you've been able to do that, then you have to test your design and measure its performance. You measure things like the bandwidth, dislike theorised by default, time, and so on and so forth. Okay? And you carry out a preset socket. Both layout will come up with an idea. You decided, you test, you evaluate, and now you want to make a prototype of it. So you design a printed, a printed circuit board of your design. And finally, you document what you've done as an egg. You write a document to show that this is what I have done. That document, the information that you do becomes your lab report at the end of the course. That lab report is what is going to be a says that is what you are going to be given marks for, for taking part in this course. So how is this course going to be delivered? Well, in the previous years, this will be a lab cause it will be done any university in the laboratory and you'll be doing distance physically. Unfortunately because of the situation, we can't do that now, the government regulation, the government guidance does not permit us to do that at this point in time. Therefore, we're going to use a software LTSpice, LTSpice simulation software for electronic circuits. Ok, it gives us a very good idea of how your system will be in the laboratory if you build one type. Ltspice is a software used in industry as well. So it's a good tool to know how to use these for simulation to see how your socket is going to believe to be likely to behave in real life. Okay, so as I've mentioned, we probably can't do any in-person laboratory sessions for now. However, if teams change as people get, that might be to emphasise the new currency, but that might be the opportunity for those that are in Edinburgh to come into the lab and have some in-lab SP is the chance of that happening is very small at this present, Putting both Nessie possibility because of our hybrid delivery mode. If it happens, the in-person carries new MAC at all. Okay? Is not going to contribute to the assessment of the costs and the delivery mode. The fact that we're doing this cost using LTSpice does not diminish the learning outcome of discourse. It does not take away from what you learn in this course. Because fear, if you want to do this in cost in the laboratory. We still have to do the simulation first before they yes, I understand that there will be some things you do elaborated for instance, you cannot sue them in simulation. You can do soldiering in simulation, yes, but we believe DCF time to catch up on those if you haven't done that already. Ok, so it doesn't have any real impact on your core learning outcomes. So in terms of recourse, shade or how is this course going to, he planned to go? The plan is to have weekly timetable synchronous sessions like this one where we can discuss the essence of this is one to answer any questions. You might have your time to give you some tips and some ideas with your design. And if you have questions that I can answer your questions in real time to quiz on engagement and interaction data. The essence of that weekly live session, each of digital layer live session will be recorded. It is possible that some people might not be able to join. Then it will be recorded and it will be available on lane shortly after. There's also discussion board on lead that I've set up. This is also to facilitate interaction and engagement with the cost. You can post your question anonymously if you wish to do so, that's fine. And it also provides an opportunity to engage with other students money cause I've seen that some students have already been engaging with the discussion move his fantastic. So I can get this on some comments and replying to comments on, on this are encoded everybody, if you have something to say, to share or ask or contribute, please, please do use the discussion board and I will get back to you as soon as I see your comment, as soon as possible. Typically, we didn't eat the O2 maximum. In order for you to get the most of this course. My recommendation is you commit a minimum of three hours per week to working on your decide for this cost. Anything less than that might mean that you push too much of your work to the end of the semester. And that is going to be beneficial times you have to wash and you might not have enough time to do a good job. So suggest a minimum of three hours per week on this course. Because Monroe, the activity tracker and all the learning materials you need are available on net. Did right now, as we speak up, put up one day. And I've decided cost the truck has such a way that what you would do pretty weak, broken down. Obviously it becomes easier to follow that erato follow what you have to be doing on Wiki's basis. So anyway, an introduction, well, because is as I've mentioned, we need to use this, get competence or pumps to design some systems. But those subsystems AFI function to perform. The function that we want to perform is that of optical transmission. That is, we want to use, dissociate them. You decide to transfer information from 1. Oh, that you see lights. Okay, so for that to happen, we have inputs, which is our information. We have an optical transmitter, which is going to be a light source. It could be an LED or a Liza, both for the purpose of this course, we are going to be using an LED can then try with dark light that is carrying the information travels to a medium. That medium could be an optical fibre or it could be free space. And we have a light sensor detects that picks the light and recover that information for me. So the light sensor, in this case, when we call a photodetector, there can be one of these three. Can be a PIN diode and APD or is part APD represents avalanche photo diode, uninspired represents single-photon avalanche detector. For the purpose of this course, where you see the one in blue, a pin diode, that is a P material with intrinsically or individual n-type material as a photo diode. Where the emphasis is not to know about these materials as this device is in detail. Know our emphasis is on to use them, which is of sockets, okay? And once we use the data to the, we get information out from the optical receiver. So in this course, we are going to be particular about kinds of gates. A pen. Yes. So we will be walking here. This is the limit of your design. We want to design an optical receiver and optical transmitter as already been designed for you to use. We have that already, but now you want to design an optical receiver plus a video on land called the cause suddenly video is a short demonstration of optical communication, and it also summarises what it would be great if you have not seen the video. I encourage you to please have a look. So before we continue, Can I just ask a quick cheque? Has anybody seen that video? You can type on this on the chat box if you have. If you haven't, that's okay. We still have time to have a look at it. Very good. So somebody said the series, so that's fantastic. So if you haven't, please, Very good. Thank you so much. Very good for you, but thank you to everybody for boundedness. Fine. Excellent. Thank you. Okay. So for those that are not seen it please, I encourage you to have a look. It will give you a clear idea of what you'll be doing and what you need to prepare for in discourse. So he comes to your own obstacle. We see by design, I've provided for you a block diagram to guide you in your design. The first thing is we have an intensity modulated optical signal coming in, that is the light signal, the US data on top of it. This one is a light signal with data on top of it is coming in the context of a photo detector. And as I mentioned, we're going to be using a pin photodetector, PIN photodetector. Hadi beginning I mentioned about trans impedance amplifier. That is a coins to voltage amplifier. The output of your photodetector is a colleague signal. Okay, is coined. But what the TIA does, this block, what it does it convert that current into a voltage. So as an amplifier, it takes, call it as an input, and the output is a voltage. Therefore, it is a current to voltage amplifier, hence the name trans impedance amplifier. Because if you look at the ratio of the output to the input, the output is voltage. The input is code that we shall becomes impedance, hence the name trans impedance. Trans means from input to output, eerie transpires from input to output. So trans impedance amplifier is the first stage. After that, we have what is called a DC blocker. Dc blocker is a high-pass philtre, SPF, high-pass philtre. What happens is that the signal from your TIA, We have some DC offset, we have some dialect colleague offset. That is signal, a signal that is the DC current that is there. But that this evolved, it carries no information. It has nothing to do with your information, but it's just an offset from your op amp. If you remember from your op-amp, you must have learned about DC offset in APA so that this is not needed is in w2 sickness, so to speak. Therefore, the essence of the DC blocker is to remove that on one tape DC voltage. The last point is Sallen-Key active philtre that she mentioned that your DC block, I say passive philtre that is going to use discrete components. No active component at all. No, no, no transistors, op amps in your DC blocker is going to you, is a passive philtre. Your salon key is an active philtre, meaning that's inside the Sallen-Key philtre. That will be something like an op-amp in an active component. Okay? So this is an active philtre asked two stages. One is the preamplifier and the other is a low-pass philtre. The two of them joined together is inside the Sallen-Key active philtre. So we amplify the signal coming in and then we feel TI C low-pass with a fourth order look past. That is what I want you to design. The fourth with a low-pass philtre here. And we have low-pass philtre to, again, to introduce another filtration of the signal. Why do we feel that? Well, we want, our signals will be to a particular bandwidth we want to design to a particular specification. So any signal outside of our specification, we don't want it. Hence, the need for this low-pass philtre. We want to reduce the amount of noise in our system by limiting the frequency occupied by does it. Hence, the use of a lowpass philtre that we amplify the signal once again and we have the signal out into oscilloscope. What comes of the oscilloscope is what we observe the essence of the ASI, those goods to take measurements, to understand the properties, the characteristics of the signal that you've received. This is where we take our measurements in the oscilloscope. We need to take measurement. Then you do the same thing. If you are doing your work in person, in a laboratory. But as we're doing it on a synchrotron software, you can also use oscillates. The software in the LTSpice software to measure. To repeat, your task is to design the receiver and you need to characterise is performance. That is your task on this course. What are the specifications? While this table summarises what you've been asked to design to, for instance, the power supply is plus or minus 15 volts for the diode as an output of one micro amp. And it's got a capacitance of two picofarad and so on and so forth. We have this particular variety. I ate 40 DC blocker, low-pass philtre, amplifier one, amplifier two. Everything you need is in this table. This is a guidance for your design. One that I want to emphasise is the specification for your TIA, for your trans impedance amplifier. On purpose, even given a frequency range of between five megaHertz and eight megahertz. For your bandwidth. Division for that is very simple, such that you have the freedom to choose what bandwidth you want. Again, given that freedom means that two people, it's almost impossible for two people to come up with exactly the same design, because you have quite a wide wage to choose four. Therefore, it is not helpful for you to copy your friends this time. I will find out quite easily. That is not encouraged. You can point. So you have a quite wide when to come up with your own design that fits into that particular specification, right? And that is the reason why we put that in there. Please note that I've put in some sucky suggestions. It because Manuel, That was the end of the Manoa there to guide you as an example, how do I design a TIA? You have this suggestion. You Manuel, what ETI issue look like. Also provided zone design equations. We have the second, I'd way decide the component values. What value of resistor should I use? What value of capacitor should I used? The design equations that will help you in choosing those values is also introduce the equations are also in your lab manual. Please have a look, an affiliate. You are welcome to use your own design that is highly encouraged. If we know how to do so, you're encoding to come up with your own innovative ideas, but innovative design, I strongly encourage you to do so if you know how to, okay? And if you want to explore and try something out, you're also encouraged to do so in this course. Some active components are pumps that I recommend for us to use on this cause or put their data sheets on land as well to guide you on how to use them. It is helpful if you start to simulate each subsystem as independent IO subsystem of your design. For example, you might take the transadmittance amplifier and you decide that on its own. And text you tested amnesia is working. You design your DC blocker on its own and test to Russia is working under. You can join the two together and ensure they both walk and then you continue. That way. This is a repetition to to let you know how important it is. Walk on your design Weekly. Do not leave it till the end of the semester. Don't crash it. You cannot catch this because you have so much to do here. Okay? And the best thing is to do it every week. And you need to leave enough time to get your report at the end. Okay. In Costa Rica in shadow that are put on lead have left about three weeks for you to get your report. That is my suggestion. That is the minimum time. I think you would need to get a very good report out there. In terms of assessment, you will need to submit a receiver schematic diagram. That is, you want to design these circuits. What is your idea? I need to know that. We need to assess that your idea and that idea after the presented in the form of a schematic diagram that is, allied communists connected together, already joined together to perform the function that we specified for you. Okay, that is due on Tuesday of week four. The submission is on learn online. Okay. Is due on Thursday before online. And that accounts for 30% into assessment of the costs. That schematic diagram. This schematic diagram you submitted in week four, might be your initial idea. It might change as you continue thus find, you may find out that as you continue to test and experiment with it, you need to change parameters, you need to change values. That is perfectly fine. What is submit in V4 is your initial idea. That is why you are starting from what you think you are doing, what, what we've got to buy data. That is what I expected. It should be a complete one, But it might change as you continue with your design. And then at the end of the semester, we want to see a lab report that is due on Thursday of week 11. Again, that submission is on online on Learn the lab part as the specification of a maximum of ten pages. And in the lab in a course madman, you see what I expect to see. I've given you a breakdown of how of what to include in your report. Okay. And finally, they your design or your PCB layout file should be put together with your report as a single folder submission. And all of that accounts for 70% of the assessment. All right, so once you've done your design on Earth, despite I DO your PCB layout, you put down together with your lab report into a single folder and you submitted in week 11. And that finishes your course submission. And in total, we have represent for the assessment. In terms of grading, detail, discussion about degrading in the lab manual by go to the main points here. So what we want to see is the completeness of your design. Your design can need Kali out. Can you design, carry out their function that we've asked you to do? For instance, can it detect an optical signal? You could combat information. And that he asked to meet our specification. The bandwidth of your design must be between 58 megahertz. That is a specification. The clarity and originality of design. If you give me a schematic diagram, is it clear to read? Can we see the values? Can we understand the component values that you have used? Formula schematic diagram, for example. And then we'll look at a quality amount of offset, the distortion. And you've our Lesbos because in your mind while you've been asked to carry out some tests. So that's number three bullet points is to cheque your yogas bonds to those questions and to do tests. You do the PCB layout will look at your PCB an hour well, into your PCB layout, one thing we're going to look out, your PCB is the size of it. It is so big that it's going to cost too much money? Or is it about the right size for the amount of components that you have on it. Then we'll look at the performance of your system and the results that you put in your report. Finally, it goes to your report. How well, a few within your report. Well, if you put your report together, what is the structure? What is the organisation of your structure of your report? The completeness and accuracy of information presented. Information about this is in your lab manual to guide you. Remember, when we are reading your report, you will not be day to explain what you've written down. So it should be clear enough for us to make sense of what you are presenting. Okay? And to summarise, this is an illustration of the design challenges that we have so far. So far you have an idea or a concept. That idea is in the form of the block diagram that I showed you earlier. You translate the block diagram into a schematic diagram. Here. That is, how are those companies joined together in each block diagram? What decide do I need? And then how are the joint? You get a schematic diagram. Once you've done that, then we go into prototyping on the bread board to test that initial idea. Now, because we are doing this using LTSpice emulsions. Prototyping is been replaced by LTSpice. This is the one that is now LTSpice in this case. So we're going to do this prototyping if you like, you seen our software LC space. So that is DAF is as it's been replaced by LTSpice. Based on the measurement, based on the observation from the simulation, you can refine your design. You make improvements to make it better, make it fit into your specification. When you are happy that yes, It's within the specification that you won, you now proceed to PCB layout. In other words, I want to make the board itself, I want to make the design. We'll find our product, which are like once you make the PCB layout, we're going to do this in this course and as a software to use for that. Define our product is now the manufactured PCB. Ict's. We are not going to do this stage in this course this year. In the previous, Yes, we did this stage, but because we are doing it online, we are not going to make the final PCB. You sang. Once you have your PCB layout, if time permits, maybe towards the end of this. Because if we allowed impressed and we might consider manufacturing your PCB for you. But as at this stage, we are not going to between defy now PCB print out. We're going to use the PCB layout as the last action in this course. So in terms of what should I be doing, this is week one, What should you be working out? Well, in week one is our introduction and as is this session we're having now, I think I've told you what this course is all about. I think I've told you what you be Lenin. And I think I've discussed with you, was Keil, you acquire by taking this course, you learned how to design electronic circuits. You learned about optical communications, and you learn about how to write a technical report. Tiestall device, what is called simple RC, acute first-order philtres are pushing to amplify our golden rules. What are the basic rules guiding the use of op amps in watching amplifier, non-inverting amplifier, besides just to refresh yourself when it comes to us. And that is what I expect you to do in week one. And that has been covered with lecture one with us, this material, the video of this session is going to be put online shortly after was the lecture slide that I'm using now is already online for you to consult athlete I did, if you will, to do so. If you money to do all of that in week one, that's fantastic. In getting ready for week two. Our encourage you if you have not done so already, to download the LTSpice software. I've given the link there. It's a free software to download. It is made by analogue electronics, is accompanying electric electronic comprende analogue devices. They've made that tool available for free so you can download on your computer. How encourage you to do so as soon as you have the time and try to find your way around and try to understand how it works and to open a file, how to save your file and things like that. That's a huge resource about LTSpice, particularly if you go to the help file, you've got a lot of useful tips for getting started again. And the one that we'll be using for our PCB layout is called target. Yet it's also a free software that you can download. The link is provided here. I should emphasise that target is not the only tool for P3. There are so many out there. Like I knew, some of them are free, some of them are not free. I recommend I get because we can give you some supports on target. If you find any or L1 suitable for your need. By all means you are free to do so. It might just mean that we might not be able to support you. If you have some technical challenges with our targets, we can support it because we have it installed and we are people know how to use targets very well to support you in your cost. Alright? In week two, excuse me, a week to issues that. Thinking about your design, look at the block diagram, each block in Dakota gums to think of what should be inside each of those blocks. What should be inside your TIA, or should be inside your DC blocker, and so on and so forth. You should start thinking about that. Start thinking about your design specification. And you design each subsystem by hand. In other words, you work out the component values for each one. The design equations to do that are already in the lab manual is, I think is very straightforward to do. So that is what I expect you to be working on any face to with the fool's shadow is on Lennox whiteness inside your lab manner. And what I'm going to do is I will take a pause now and I'll take some questions. And then we have some international after we shall go on to learn to show you where all of these resource where they all are winch. Ok. So I'm happy to take some questions and interests us at this point of this session. If you want to speak our encoding you to raise your hand using the raise hand icon on your screen. Or if you prefer, you may type your question in the chat box. So we do that for about five minutes depending on the number of questions that I get. Any questions from anyone. Is the information presented to you clear? Schumann? I'm sure my apologies if I did not pronounce them correctly. So Schumann, Yes. You and Bob? Yeah. Yes. So my question is regarding the prototyping stage, vacuum mentioned that you'll be using LTSpice. So like after the schematic diagram, when we create it, I didn't understand like what are we supposed to like? Are we going to be having some sort of a layout where we will be creating this similar bread boot structure? Or can we just simply move on to the PCB layout after we have the schematic diagram up. Okay. Thank you so much for that question. Yes. So we're not going to have the bread board layout. So once you do your schematic diagram on LTSpice. So in LTSpice, this candidate diagram and prototyping I joined together. You understand, so is front desk schematic diagram you simulate if you observe the performance, you refine your design and straight after you go to PCB layout, yesterday's know, this prototyping stage is in a way matched together. We just schematic in LTSpice. Does that answer your question? She'd been yesterday's also another one in the sense of a stupid question, but is the neatness of the schematic diagram also graded like, you know, It's supposed to be very clearly understandable or candidate like for instance, if it's a haphazard, isn't that going to be taking away a mux? So outro dumb question. But what do you think as an engineer? If I give you a schematic diagram, what we'd be looking for, something in an engineering diagram. And I'll actually, last year when he had a similar course in my schematic diagram, I had spread it across. So like at, in order to make it look table, my schematic diagram was like there was a lot of gaps in the middle and I was told not to do that. It was asked for me to compress them altogether, even though it's a rather schematic diagram, another PCB layout. So I realised that we need to make it look present APL, but I was told not to do not to leave a lot of, you know, Yakuza empty spaces. Because I felt that if I did that only then it was looking a bit neater. Superscalar. Ok. So I'll make my comment to that would be these I don't know the specific of that cause that's where we find two, that's fine. When you do a PCB layout, this PCB stage, you don't want someone's gap between your coconut because that means your PCB will be much bigger than necessity. So you want this form factor when it comes to products. So you won't easily compact to save space because space means money when it comes to PCB. And imagine if something becomes too big, it might not sell in the market. For example, say for instance, a mobile phone. So he asked me something compact to you. Now, that's a correlation between your schematic and your PCB. If your schematic if your schematic diagram is a direct representation of a PCB, yes, you don't want too much gap. You understand. But what is important for socratic ECB? Clay. It should be readable and ID numbers you put in that you also be clear and readable. You understand the idea of a schematic is you pass your schematic to someone far away. For instance, in my being added as a design engineer. And your design might be fabricated in a different country. Schematic. So dp poor fabricating your schema diagram. They don't need to talk to you. This you'll get all the information they need from the schematic diagram. That is the main idea, that is the main purpose of his committee should be easy for somebody to read. Understand what you've done, including the component values and all the connexions. Plus answer your question. Yes. Thank you very much. We work on. So what I would do is not this week, maybe in week three, when I give the lecture, I will show you some examples of schematic diagrams form for us students. Okay. Just to give you a clear understanding, he asked is D in week four. So three, we have a look at some examples of good and bad schematic diagrams. Okay. Anymore questions? His information. He sent a clear So there's a question here and he says, is the weekly session four lectures only? Or is he also to help us with our lab? So that's a very good question. I've got to mention to you also that I am not the only one on this course. I've got my colleague, Dr. Jenny, who is also teaching on this course. And I'm sure GB is available online about ionisation alkyl goods as does gimme. So if I want to show you a video, if if that's if that's possible, Jimmy. I guess I have my camera on a Okay. Good. Yeah. So does Dr. deme, Maryland and we are teaching on this course together. Okay. So you get support from both of us. And on top of that, I have demonstrators in normal semester. We have in the lab and we have demonstrators to help. Which one-to-one less points your questions. Since we can do that, we also have demonstrators available and they will be happy, particularly when you pose a question on the discussion board. It might be myself and maybe Dr. Jamie boy might be one of the demonstrators that will respond to your question. And when we do weekly sessions, you are also free to ask your question. In that way you get a one-to-one lesbians TO question. So you have so much opportunity to engage with the course and you are so much opportunity to interact with the cost or you are so much opportunity to get support on the cost. So that is the way it's going to. I don't know if that answer your question. A mirror. Anymore questions. Anyone else? Okay, so if there are no more questions, so what I will do is I'll quickly walk you through what are put online. Thank you so much, Jamie. So again, before I go to LA and very quickly, you are also free to send me an email. If you prefer to contact me by email, you have my email address. That is also fine. And I'll do my best to respond to you as soon as possible. Typically, we didn't eat the O2. Okay, back to you on your question. So I'll quickly go onto land to show you how the cost has been. I again, unstructured in there. Right? So I believe my screen sharing now. So if you come onto land on the left unpaid, You see the welcome information and that is what you have here. This is a welcome from myself and Jamie onto discourse. And I've also listed the leaded outcomes on here and everything about it takes a short video. The customer is attached here for you to have a look. Next to that. On the left-hand side here, I believe you can see my Corso, we had the discussion board. If you click on this, then this is where you can post your comment. You can see some of your colleagues are already engaging with the cost. If you want to post anything or say anything, you just click on this discussion board and you enter your question or your query or your discussion going about you want to share, you get in here. It cost materials, as mmm suggests, that tells you, that provides all the information we need. So this is the cost plan and this is an activity tracker at the same time discussed to you what is in week one and our viscosity, what is in week two. Week three is a draught design ready for week three. In week three, I will be giving a lecture. And that pleasure is, tends to consider. When you finally start to make your design for a sample loading effects. In seconds, I will be doing that in week three. Week four, you must have completed your Schematic Diagram and be ready for so for submission. And you stimulate, you start your simulation at the very latest in week four, you start the simulation in LTSpice for guidance, CEO cost manner. Week five. Test. Are you fine tune your design? You optimise your design to make sure that it meets the stipulated specifications. For guidance is your cost manure as well. We 67 is now to carry out your design characterization. That is eukaryotic measurements as instructed in the cost Monroe. And by week eight, you must buy vacate. You should be on your PCB layout. Get familiar with the software you want to use. Tangent is an option, but there are many other software you can use today. And between weeks, 911, You should be working on your final report. Ie, the outline that are put together as a guide for your zinc guide. And in this folder You see the cosmetic Afghan resource. Here. This is the video I was talking about because somebody video, please have a look. And we have to cost Monroe in this folder. And we have the lecture slides. If I click on the coastline where you can see on the left here, we have the table of content whereby you want, just click on it and it today, because man will cost money itself. And just open that quickly. And that is the manual that we use for this course, okay? And it's got all the information that you need in there to get started. All right. So thus vague on purpose that's been made detailed for you. Okay. I'm just trying to see if there's any comment from the chat box. So that's a question. Does is she we use LTSpice to design the schematic diagram or we have to. So when it comes to our schematic, don't draw by hand. You can go by hand. You own your own data, your own scrap paper for your own purpose. But the one you want to be hit as to be properly done, we'd do you write software, for instance, you can use your targets software to the schematic. You can also use the LTSpice. Do it, and you can use software to draw your schematic, but do not do it by hand. Okay, that's fine. So we go back to the course materials. And so you can see the Costco is there, as I've mentioned. Because meanwhile, the datasheet of all the components and LTSpice MPCP resource is that here. You can find Getting Started with LTSpice, PCB layout, tutorial, and crash course on how to use target, and a quick reference guide. These are all the information you will need to do your work. Understand the two pans that are recommended are LM 6171 and LM 31. Eat. Both of them are from Texas instruments. For the sake of uniformity and conformity. These are the only two that you can use. Do not use any op-amp outside of these two. Going to stand for the sake of uniformity. This ones, any of them choose suffice for the design that we want to make discourse. And finally, I've got a lecture slides, a doorways in. Lecture one is what we're having today. Lecture to next week will be on LTSpice basics. The time for this lecture two will be communicated to you very, very shortly. Dean versus working on sorting out the timetable, you will be informed of the time of that lecture two, it will be sometime next week and the week after we're talking about teams that will make your designs better. In particular, we want to look at loading effect. If you join two different subsystems together, how did they affect themselves? So that is important to make sure that your design, at the end of the day, it meets the required specifications. And so decided to lectures. Thereafter, after week three, we're going to have live sessions, but it will be more of question and answer. It will be more of interaction. You'd be more of giving tips. You'd be more of responding to your questions by in terms of lectures VR3. And those are the three that are already listed. I believe that would be the end of my presentation. Do you have any questions? And is that clear to everyone? I'm happy to take questions for the next seven minutes that got left. And to answer what comments you might have. Does the question is, are there any specific formats? Are steps when we are doing the report? Well, for your reports, you need to I believe it must have within some report before technically, but if you have not. So I will go back to our stock sharing now. Go back to my lab, Manuel. And I will show you what I've said in the to help you with your report. So just give me one minute. I know. Open the lab manual to give you some more information on how to write your report? Exactly. So. Right. I believed my screen is share in now. So if you this is the lab reports that I'm on. So if you go down into your lab, we got the beginning is going to tell us the project solely because what we need to do and equity like that about your design. This table here is your shadow. What you'll be doing, the tasks that you'd be doing is a step-by-step guide to what you'd be doing. And once you've finished all of that, it goes to assessment. And we have a section on the lab report. This section here gives you the information that you've asked for and that is what needs to be in your lab report. Okay. The organisation and everything you need to put your report is stated here. So you need to think about it, that GOD post must have some form of introduction. Most ask some form of aim or objective of what you want to do. And then you show how you've come about your design. You give us like your design. And I will come about the component values that you've used in your design. And then you talk about you noticed like the measurements you've taken, you've taken that is yet the characterization and that is already stated in this table. And then you discuss that and put all your resources in the and finally, your your report must have a conclusion to say this is, you know, decoction of the work that I've carried out. Does that answer your question? Answer does that answer your question? Good. Thank you. Answer any more questions from anyone? Is it clear what we're supposed to do here on this cause? It's anybody confused? How is everything clear once you are supposed to do Uruguay? We now at your show, what's to do? Yes. Okay. So everything is clear. I can hear. That's thank you. Thank you. Everything, clay. So just in case you have questions. Just in case there's something you want to clarify. Please feel free and get in touch. Do not wait till the end of the semester. Do not wait until week four, where you have to submit your schematic diagram before you with your questions. We are here to support you. We are here to help you through this course. So you can end gate, as I've said, you can send me email. You can use the discussion board and you can use the weekly meetings to carry to carry on. They are not, we are not going to have tutorial or seminar for this course and assign. It has no, it's not a cost that is suitable for tutorial and he's trying to construct a suitable for seminar guesses, a practical lab course. Therefore, everything we're going to be do, everything that we do will be confined to this weekly sessions or to the discussion board online. So there's no tutorial or seminar after. And this will be the final call. If anybody has questions or comments, we have about two minutes to the end of this session. Excellent. So if there are no questions, I will say thank you so much for taking the time to attend this session and do enjoy the rest of your day and see you next week. Thank you. And bye, bye. Bye, Bye all.
