Hi Lain, thank you for sharing this amazing brainstorming classes. As Telcom engineer i find your teachings to be the fundamental and core of signal processing. I now subscribed!!!!
Nice - thank you. The frame at time @19:00 should be printed as a poster and hanged on the wall as reference for all system work. In fact it makes great poster. I studied those things over 20 years ago, and I still need them.
I'm so glad you think so. As you've probably seen, I put a "summary sheet" pdf image of each video on my website www.iaincollings.com/ Here's the one for this video: drive.google.com/file/d/19uTb-3W1G0ZfXCPU0aOfeKCZFFmQVD9p/view
Wow, oh wow, oh wow! I have found my candy store! I've been searching YT for such a channel, & I finally found it! I've always loved signal analysis but have been lacking fundamental understanding of many topics. I absolutely love this channel!
Currently studying Advanced tellecommunication at QUT. I have supplemented my learning with your amazing content, it has been instrumental for my understanding of OFDM!
Sir, You are an excellent teacher. You teach an essential thing well beyond the simple transmission of knowledge: the desire to learn. I left my engineering school more than 37 years ago and to transmit my analog knowledge on my youtube channel, I fully appreciate the high quality of your teaching. Congratulation
Thanks so much for your very nice comment. I checked out your channel. It looks like you've got excellent content - I just wish I could remember more of my schoolboy French lessons. Je ne parle pas Francais - is about all I can remember, unfortunately. ... oh and Vive la Tour! ... looking forward to July! 😁
Oh my God, I've been crying and breaking my head and breaking my head and crying cause I wasn't able to understand these things. You've made things so much better for me and I can't thank you enough. I do have a question. What does t and T stand for? I can't wrap my head around that.
I'm so glad you found the video helpful. The variable "t" represents continuous time (as an input variable for the function). The variable "T" stands for a specific value of time that represents something specific about the particular function (eg. the period, the switching time, the sampling time period, ...)
Sir, simply amazing work, and having seen your videos i am writing this even before viewing this one! which simply means that you are the GOD of your domain 🙇
Going for an interview at an IIT ( KGP, India ) to pursue Masters on Signal Processing, and this video just summarises everything I studied for the topic. Please put up part two of this video by tomorrow. A humble request
Hi Professor, Thanks for the video. The received signal through a wireless communication channel is often represented as the product of the complex channel gain and the transmitted symbol in a given coherence time interval. Could you please explain what is not the convolution?
It _is_ convolution ... it's just that in the cases you're talking about, the channels are "non-dispersive". In other words those channels don't have inter symbol interference (ISI). Which means the convolution reduces to a simple multiplication. These videos might help: "What are Flat Fading and Frequency Selective Fading?" ruclips.net/video/KiKPFT4rtHg/видео.html and "What is Intersymbol Interference ISI?" ruclips.net/video/I087FUvW2ys/видео.html
Hi Ian. Great video. I have a video suggestion: which are the essential mathematics to learn (or more like to master) for signals and systems? Thank you.
The video on signals & is fantastic! You should really share your knowledge with college students in East Asia like my home country CN, their lectures simply suck. (Maybe you could join the Bilibili!) BTW, Prof. Collings, I am really looking forward to your reply about my joint Ph. D. application.😊
I've looked into Bilibili, but unfortunately I don't speak or read mandarin. Sorry if I've missed seeing your PhD application. Can you please re-send it?
Hello, a generell question: after filtering, can we say that the noise power is 0 mW? Or is it still in B and the filtering just canceled the noise in the frequency range below and above my transmit bandwidth B (so it is always there and does not vanish anyway)? Thanks a lot.
Bit confused with the first point - how can you replace the t variable with anything else and still have the same signal output (shape). E.g f(w) is by definition a different spectrum than f(t)?
I think you're making the (common) mistake of thinking that a function is defined by what is in the brackets - but that's not the case. The thing in the brackets is a variable. It's not the function. Perhaps this video might help to highlight what I mean (although I think I probably should make a seperate video to explain this more directly): "Fourier Transform Duality Rect and Sinc Functions" ruclips.net/video/rUgBhEpeqxo/видео.html

This is exactly what I have been looking for for a long time! Thank you! I'm going to watch every video on your channel!
I'm so glad you like the video. All of my videos are in categorised order here: iaincollings.com

@@iain_explains Wow you were thinking way ahead of me. Thank you so much for your great work and for your amazing contribution to our community.
@@iain_explains I will print it and hang it on my wall.
My pleasure. It's great to know that my videos are helping people.

That's great to hear. I'm glad my videos have been able to help.
Thank you Mr Ian. The service you provide with these videos is invaluable. The clarity of your explanations are truly commendable
If you could create a video on the Green's function and its connection to the Dirac-delta function, that'd me much appreciated
Thanks for the suggestion. I've put it on my "to do" list.

thank you for your efforts. I hope all Profs learn from you how should be explained such complicated concepts
Thanks for your nice comment.
Thank you so much prof Iain
Waiting for part 2
Sending love from Syria
I'm glad you liked the video. Part 2 should be ready on Monday.
This video is a life saver,thank you so much
Glad to hear it was useful!

Thanks Professor. Good for students who are rusty.
And also for students who needed to pay more attention in class 🤔😁

That's great to hear. I still need to finish making the Part 2 video. It should be ready on Monday.
@@iain_explains Thank you.
God bless you
thank you Iain， i hope you make more of this， thank you
Part 2 should be ready next week.
wonderful teaching. Thanks a lot proffesor
Glad you liked it
Nice explanation ❤

How the amplitude of convoluted cos got 1/2?
This video should help: "Fourier Transform of Cos" ruclips.net/video/McITNfo3LKc/видео.html
I wished there was a RUclips beck to 2003 when I took this subject
A lot has happened in the past 20 years! 😁
I know my classmates are soon going to be here... alll of them
Great. I’m glad you liked the video. Please spread the word.
Great job.
