Essentials of Signals & Systems: Part 1

An overview of some essential things in Signals and Systems (Part 1). It's important to know all of these things if you are about to take a final exam on the subject, or if you are wanting to perform signals analysis.

Part 2 in this pair of videos:

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!

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!!!!

[AUDIOETRADIOATUBES]

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

[Lyle-In-NO]

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!

[elyepes]

Thank you Mr Ian. The service you provide with these videos is invaluable. The clarity of your explanations are truly commendable

[sandeep]

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 🙇

[pywrwgt]

thank you for your efforts. I hope all Profs learn from you how should be explained such complicated concepts

[a.martini]

Thank you so much prof Iain
Waiting for part 2
Sending love from Syria

[uncleroq]

Thanks Professor. Good for students who are rusty.

[sudiptoshyam]

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

[stephensu]

thank you Iain， i hope you make more of this， thank you

[Suryateja]

wonderful teaching. Thanks a lot proffesor

[fifaham]

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.

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.😊

[shauni_jade]

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.

[nithinbabu]

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?

[nelebauer]

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.

[divyanshmittal]

How the amplitude of convoluted cos got 1/2?

[nevis]

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)?
