This is a jaw dropping explanation that actually reaches small-brained audience such as myself! I cannot applaud you enough for such an honest work! Thank you so much.
This video should have multi million views to render justice to the effort and intuition put on creating such a explanatory and clear content … powerful !!
Mathematical Tools & Techniques are main foundation to our modern & future technologies. Lot of Thanks to ancient & modern scholars,who develop Mathematical Technique (Trigonometry, Calculus,Probability, Algebra...etc) for solving complex problems in real time scenarios especially in field of Science,Engineering,Technology & Architecture.
Will you be coming back? I encourage you to do so. You could do a video on P.I.D. as your channel would be incomplete without it. Use real world examples: sluices on hydroelectric facilities, cruise control on cars, etc ...
Excellent animation! I also love the new perspective brought by the explanation. Are you planning on taking a more pratical (irl examples with maybe pseudocode) or theoretical approach for the rest of the series (pun not intended)? Cheers!
Most certainly, I needed the hardcore theoretical interpretation first to land the coming practical aspects. I am planning to proceed using MATLAB and Mathematica so viewers get comfortable with Fourier transforms as a tool. Then I will progress to a vibration analysis project that puts everything into practice.
It’s just the beginning and I am learning so much from viewers like you about what gaps to fill. The whole purpose of this series is to practice vibration signals because I believe they can be the best practice of signal processing. I am building the foundations for that. Each highly abstract video like this one will be followed by a more elaborate simulations using software packages like Mathematica and MATLAB/SIMULINK models.
@@TheoryOfControl interesting and i like the idea of boiling it down into base physics not necessarily electronics as it could be used to describe more mechanical motions. how it would connect with seismology could be interesting although im not sure how much is there or how technical that may become. definitely going the right way about this so far though, good job.
You should have concluded by showing how this allows the finite transform to produce meaningful results using a sweep of chosen discrete frequencies, when mathematically (using an infinite signal) only the exact frequency will produce a spike and being off by just a little bit will be zero. With the finite window, you get increasing spike as you tune into the exact frequency.
Is it just me, or should the signal move in the opposite direction here 2:16 ? (If x-axis represent times) I really like the way you phrase some stuff, coincides and validates how I think...
The “landing” effect is more of an analogy than what actually happens. Think of how multiplication works on two signals, every nth sample of the first signal is multiplied by the same nth index of the second sample. If you checked the sinc function you’ll notice it’s centred around zero meaning if we multiply that by the spikes signal. Result will be zero because they are not aligned. Convolution on the other hand takes the sinc function sample by sample and slide across the spike signal, still most of the new signal is zero but when the spike matches the sinc, multiplication is non zero. Here’s a video that visually helps you see convolution in action. ruclips.net/video/acAw5WGtzuk/видео.html
3Blue1brown now has a competition 😎
This video is even better !!

A stunning presentation. Technically rigorous. It has everything I want to know or say about Fourier Transform. Thanks -infinity to +infinity :)
This is a jaw dropping explanation that actually reaches small-brained audience such as myself! I cannot applaud you enough for such an honest work! Thank you so much.
Fully agree. Excellent explanation with color graphics but background music, for me, kind of annoying.
best FT explanation and visualization ever met

I studied this stuff on 2004,before all those RUclips videos were available.
Now,it's much more easy to understand
Thank u for such clear explanation
Great Explanation. Thank you very much
This is such an amazing video : best Fourier Series/Transform video 💎 … and I have watch all top science channels on this topic before 👏👏👏
Thank you for putting this out, can't wait to see more videos from you on this topic in the near (hopefully) future.
This was immensely informative
This is a piece of art
You have convoluted art and science. Congratulations for this amazing piece of work.
What a beautiful brain boom. Thank you. I have been mystified by this for too long.
Great video! Grant's Manim library is all over youtube!
Thank you for the wonderful explanation! Great work🎉 waiting for your new updates.
Thank you. You have explained it clearly. Very good luck with the rest of control theory topics. Waiting for the same for Laplace transform.
Great video.
Thanks for making it.
This is amazing, please make more.
Bravo, great job done. Thx
Wonderfully explained!

Lot of Thanks to ancient & modern scholars,who develop Mathematical Technique (Trigonometry, Calculus,Probability, Algebra...etc) for solving complex problems in real time scenarios especially in field of Science,Engineering,Technology & Architecture.
Just WOW!!!
🔥🔥🔥 Yo niiice keep it up
Fabulous vedio!!
Great one, thanks!
Brilliant...and that's hard for me to say. Well done
Awesome!
Work of art
Jesus, you got a fantastic opening analogy I ever saw on RUclips phy.
Super...
A superb presentation
Amazing videos with great animations. I’ll use manin to make videos to teach kids he numbers and how to count. Thanks.
Awesome ❤
Man the prism analogy really hit me hard
very good ...thanks

Super stufffff
Came from reddit, good job sir!
thanks dude this is very heplful

Very good
The best ever.
Thank you!
Awesome video! Keep going
Why this excellent video has so few views?? Tube algorithm gone rogue? ..

Are you planning on making more videos? You’re really good at it.
Amazing, could you please do videos on Laplace and Z transform.
damn i slept so good
U r better than 3blue1brown
thanks a lot
How come you have only 2k subscribers?!
Fantastic video! 6:55 ('here is our FFT' or did you mean to say 'signal'?)
this may take me a few watches to fully absorb but very interesting and well explained non the less. what do you have planned next for the series?

Great lecture
Don't quite get convolution at the end, especially the "land" part

안녕하세요. 간결하고 짜임새있는 설명 감사합니다. 스마트폰 속의 수학이라는 주제의 교육용 학습 영상을 제작하려고 합니다. 자료로 참고해도 될까요? 정확한 출처 기록 후 사용하도록 하겠습니다. 감사합니다.
How do you create the animation? What is the name of the program ?
Plz add Fourier photo like newton
Good video but inequality 0>t
Very good. How can I donate a few dollars? God bless you
Why did you stop uploading? You could be one of the top tech utubers
Maybe he died?
Go storm regal and stone mmmoth
The circle you are drawing at 8:16 seems to be cos(wt) and not sin(wt). Are you sure its sin(wt)?
What's your patreon link?
Thank you for pointing that our I appreciate your enthusiasm, I am working on that and will update it on the distribution very soon.
one must be slightly insane to have thought of these things, I have come to this conclusion.
Do you have a github?
github.com/319willy
wow, why didnt you continue??? you owe it to science for the sake of keeping new commers interested
Discrete
could this have been one single bit more useful lol.
You have no idea what you talking about.
Horrible. Impossible to understand.
