This is a work in progress, let me know if anything doesn't make sense, and I will update the video to make that clearer. Thanks for watching!

how is it possible that I have spent probably 40 hours trying to figure this out, dwelling in the dark and you answered everyone of my questions and uncertainties in 10 mins? You are my hero Simon Xu.

I waited 40 years for this! Thank you so much!

"If you can't explain it that simply, you don't understand it well enough." <3 Thanks.
-
You made only a couple of tutorials ever, but boy, are these the best math tutorials I've ever seen on YouTube... No frills, so clear! I'm so happy to have found these gems :D
-
Honestly, thanks. The DSP teacher keeps pulling out random facts about a signal from the DFT plot and i'm like: "when did we talk about this in class?" You have just saved me hours of hair pulling frustration and for that I thank you.

Simon, I cannot stress enough how impressed I am by your explanations. They are very well thought out and presented. Pity that you haven't continued this channel. So easy to digest.
-
The best explanation on Youtube channel I have ever seen in my life! Easily refreshed my knowledge about DFT. Thank you so much!!
-
This is the one video on Youtube about Fourier Transform you need to watch, and I do constantly refer back to it. Thanks. I would really like to thumbs up this many times.
-
Best video. Spent ages trying to figure it out but you are here with a short video clearly explaining it all. Much appreciated
-
Best introduction on Fourier theory I have ever come across. Thank you times a million!
-
5 years ago you‘ve made this video and since now nobody has explained it better than you did in just 10 min. Good job
-
Simply and concisely explained, saying all and only the necessary things to really grasp the concept. Best explanation on DFT ive ever seen!
-
You're a lifesaver, let the universe bless you kind sir. Thank you
-
You deserve all the praise you are getting. These videos are what I have been looking for, just like many other commenters. Thank you so much.
-
best video about this topic out there in youtube! I'm posting this after watching hours and hours of videos in 2023
-
Thank you very much, very useful! I have never seen it being explained more straighforward than this.
-
Hands down this is the best explanation of Fourier. Wonderful!!
-
you explain far better than all the textbooks i found about this topics. thank you man!
-
Now is 2024, I find this is the most clear video talking about this topic. Thank you so much Simon!

Wow, excellent presentation. You made it simple to 'digest' and understand. Thanks!
