1. Understanding Fourier Series, Theory + Derivation.

Please check this version with voice pitch fixed:

this video doesn't contain any numerical example (you can find tons of them in YouTube) instead, the video shows a derivation of the formulas of the FS and develop a idea about how it works.

my professor didn't explane any of this.. he just gave us the formulas in the end.
it makes so much more sense now... thank you..

I rarely leave any comments. But you are brilliant teacher! And you know Fourier Series inside out. Thank you so much for this lectures. This is the first time somebody explained it so clearly to me.

[sujithrao]

This was brilliant. Why cant professors teach this way. I am sure half the math professors just confuse the students more. 

[danielpremkumar]

Excellent !. If only I had the facility to look at this video 46 years ago, perhaps I'd have become a great guy today. Hats off.

I am really mesmerised at your making the Fourier series inside out. I am not a student, neither am I connected to academics. I am a 56 year old person taking some interest in scientific topics. I listened to this video not as a fiction, while listening to this lecture, I gradually became an avid learner. Thank you so much. Hope to get more and more like this.

Hi Ahmed.
I'm an Civil Engineering master student from Norway. Currently I'm using Fourier Series and Fourier Transform in few subjects mainly dealing with structural dynamics and sea waves analysis. I learned about FS in Bachelor studies and used it before, but I have never used FT.
I find your video very useful. I haven't seen such a good explanation of this topic so far. Thank you for this!
Cheers mate :D

I completed BSc in EE back in 2013 in Bangladesh and a lot of these signal related math was forever out of my grip because they felt so tough. But that's only until now !!! Currently I am doing MS in Germany and I am trying to fill up that math emptiness inside of me from youtube tutorials. And it's paying off. Thanks a lot for your contribution, I am regularly following and improving.

This explanation is phenomenal. It just did not explain Fourier series, it also explains the foundation for future modulation schemes like OFDM.

Hi Ahmed,
I'm from Turkey. I'm also EE. I thank you for your effort. Congratulations to your simple expression.

[aminmm]

I'm only at the 6th minute of this lecture but I'm already happy someone made the effort of explaining the basis of the FT.. May Allah reward you man! Greetings from Algeria

[rshaikh]

excellent explanation for anybody who wants to learn fourier series... brilliant professor and his way of explaining...

[pepe]

this is fantastic. explaining fourier series & stuff without shoving weird crap down our throats. starting to figure this out. im gonna watch this over and over again over the next few years and i'll eventually get it. but im already understanding key concepts now. fantastic stuff

[cledieu]

Hi there !
That's awesome work. Very easy to follow and perfect balance between formal proof and giving a feeling of what it's all about.
I'm glad I found your post.
Can't wait to watch the other vids now.
Thanks a bunch !

[abdallahsani]

Such a brilliant and elaborate explanation. I wish textbooks and teachers would give this level of intuition. I can't like this video enough. Thanks a lot. Ahmad Isam

[medoadel]

بص انا اتفرجت ع ناس كتير بس فعلا انت اثبت لي ان العرب ناس عظيمة ...شكرا ليك شرحك فوق الممتاز

[simonetruglia]

In my opinion, one of the best video on the web about this concept!

Really really glad for this!

This is a masterpiece

[TheDhaval]

Excellent explanation, very easy to follow, easy to visualize. Thank you.

[aldenfisher]

Best mathematical approach that I have seen to understanding the FT!

[rotsen]

i had never understood this concept until now, thank you for making the world a better place!!!!

[nadunwijeweera]

Excellent demonstration, Thank you very much for sharing this
