Discrete Fourier Transform - Simple Step by Step

[@haimijordaan1353]

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.

[@charliebolton5531]

I agree, somehow it was this video, after I already tried for 1 month to understand, this one might be the one that helped me finally get it!

[@g7k993]

without the 40h this video will sound alien to you.

I choked up when I saw this was posted 9 years ago...hope you're alive you smart human! Very clear and useful definitions and demonstrations

[@louisarquie6159]

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

[@Django1847]

You waited 40 years not for your wife and children but for Fourier Transform video. I respect it.

[@mafia12saleh]

HAHAHAHHAHAHHAHAHA

[@trung-tinvo-inh8806]

Thanks for your honesty, my first contact with Fourier Series was in 1985, just a few years short compared to yours :-)

[@sunsean3426]

That means you still haven't understand the process of Fourier Translation for so many years? I think it is the sadness for the educators and students. In China, I suppose most of the students in colleges even teachers don't understand the essence of Fourier Translation. When I studied in college I didn't realize this, I turn round and find this after so many years.

[@luisff7030]

After waited 14610 days it's finally release! and now as the people of this planet know the true behind the DFT, a new era will begin.

[@satanaz]

best video about this topic out there in youtube! I'm posting this after watching hours and hours of videos in 2023

[@HamzaNajahOfficial]

"If you can't explain it that simply, you don't understand it well enough."

[@juniorcyans2988]

That was how my professor did his job. He seems enjoy mystifying everything to confuse us, and his strategy works, because those silly kids believe he is super smart. What the hell?

[@unknown8088928]

Holy crap. Thank you. Why is it so hard for the rest of the world to explain this properly.

[@tomschubert9725]

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

[@ballentinems2]

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.

[@davidcian4240]

You made only a couple of tutorials ever, but boy, are these the best math tutorials I've ever seen on KZbin... No frills, so clear! I'm so happy to have found these gems :D

[@nikhilnagarkar7422]

Hands down this is the best explanation of Fourier. Wonderful!!

[@gloriajing7268]

Now is 2024, I find this is the most clear video talking about this topic. Thank you so much Simon!

[@helmutalexanderrubiowilson6835]

you explain far better than all the textbooks i found about this topics. thank you man!

[@SirSeaKing]

You're a lifesaver, let the universe bless you kind sir. Thank you

[@Copelion]

This is the one video on KZbin 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.

[@pherchuz]

Was so hard to find someone that actually did this step by step, best video I've found on the subject!

[@guest9580]

Best video. Spent ages trying to figure it out but you are here with a short video clearly explaining it all. Much appreciated

[@witoldsosnowski677]

All the other explanations lacked a proper example. The best tutorial on this I have ever seen

[@daviderizzotti2724]

Simply and concisely explained, saying all and only the necessary things to really grasp the concept. Best explanation on DFT ive ever seen!

[@AmeltonGsairus]

The best explanation on KZbin channel I have ever seen in my life! Easily refreshed my knowledge about DFT. Thank you so much!!

[@jackiezou4098]

Nothing is better than a good example. Thank you so much!

[@markusfischer2505]

ENDLICH habe ich verstanden, wie die diskrete Fourier-Transformation funktioniert. In 10 Minuten. 10!!! Ich saß vorher stundenlang davor und habe es nur ungefähr verstanden. Herrlich erklärt und animiert. Du bist mein Held! Echt. Dankeschön! -Markus

[@metehan9185]

Ich verstehe nicht wieso in der Klammer bei Minute 7:42 die (1) und (0) eingesetzt werden warum ist k=1 woher weiß ich das k=1 ist ? und die Anzahl von n ist 0 ? 0 hat doch keinen Wert und k wird in Minute 8:43 berechnet k ist magnitude ich verstehe es leider nicht

[@zhenniqi136]

GOD!!!!!!!THE MOST MOST MOST AMAZING VIDEOS ABOUT FOURIER TRANSFORM I 'VE EVER SEEN!!!!!!!!!

[@louism.4980]

Best introduction on Fourier theory I have ever come across. Thank you times a million!

[@Ureallydontknow]

By far the best explanation on KZbin!

[@omartarek6658]

best video regarding that point have been searching for the entire day and that video solved it out . thank you

[@ellieNC10]

Thank you so much for this, couldn't find anything else helpful online about DFT but this explains it perfectly!

[@bhaiyyu]

Thank you very much, very useful! I have never seen it being explained more straighforward than this.

[@saimanikanta7360]

I searched for a video that explains DFT this clear for like a week but failed to do so....just as a last attempt I atched this video and this made it clear........Thank you Simon Xu

[@shubhammaurya3671]

3 years, 3 Years I have been trying to understand this fourier shit, and you explained it in 10 Minute

[@刘涛-r8b]

I love the video. The explanation is so clear to unstand. I hate the lectures which nobody can understand.

[@nicolacasali8304]

I've been searching high and low for an ELI5 explanation that is visual enough for my pea brain to be able to turn this into code. Thank you!😍

[@Electrologia]

No comment... This is the best explanation I have ever seen.

[@engradilee]

amazing i spent so much time to get the concept and you simply explained everything in such a simple way

[@rvhp]

Thank you very much!!! You explained it very crystal clear...I read a lot but I did not understand it like this. I made a mistake not seeing it even though it has been available for 6 years. Great work, hats off to you

This is the best and clearest explanation I have ever seen. Brilliant.

[@vtcore]

Thanks for sharing! Best video about DFT.

[@miguelbecerra8742]

I usually dont comment in any video, but this one is just perfect! thank you so much!

[@cheymabahroun3824]

Thank you for making this nightmare way less frightening !! It's crazy how uni professors will never match your level of explanation.

[@sarveshvazarkar6668]

Yeah this is THE best explanation of Fourier Transform i have seen.Kudos.

[@MilanKarakas]

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

[@StjepanBrbot]

The best clip about Fourier transformation so far. The example with sampling 1Hz sine wave is excellent.

[@faridawan3841]

Bro, what a nice explanation!!!. I hated the fourier series and transforms and DFTs but after watching your video, Now I have a picture in mind of what's going on and Now this has become my favourite topic. MAY GOD BLESS YOU A HAPPY LIFE.

[@xM0nsterFr3ak]

Man i have spent hours, just to understand the basics and you explain them in just over 10 minutes. I wish i would have found this a lot earlier 😂

[@willcheng1702]

Best DFT video ever!

[@Sizifus]

This is so much clearer than what is written in the books.

[@lightnblack1934]

This video amazingly describes all of my question marks. Simon, just thanks for the effort man

[@mwein198]

OMG - its the first video I see on this topic that makes sense, Thank you soooo much

[@siruili7643]

Thank you! Your explanation is so clear and clean, while other videos on DFT usually take 1 hour only to make you confusing.

[@pedrolins56]

This is the best video I found on the subject so far... thank you! regards from a grad student from Brazil

[@user-vl4vo2vz4f]

Finally someone who knows how to explain this stuff!

[@takusanimasu]

Great video. You make me understand what is Fourier Transform for the first time.

[@theedspage]

Thank you for the explanation and the simple example. I am finally able to understand how the DFT works.

[@shashidharmuniswamy2620]

The most brilliant explanation I've come across related to DFT. Thank you so much :)

[@Clerence3]

Greetings from germany.. You did a great job there.. I love how you explained it so easy. At the very beginning of DFT i was so confused and thougth "this is tto hard to be a question of my exam"... and now, after your video i would prefer to get one question of this .... great job! you made my day

[@melvirpascual9428]

Now that's a good explanation. If you understand this the other parts of the fourier transforms become easy

[@shamsigamer4107]

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.

[@magnusonx1]

You see, THATS HOW YOU DO THIS ! ! I wish my professor would watch this. Learning this would be SO much easier.

[@ivanverdugo2931]

Best explanation I've seen. The only one that made me understand the ecuation (not having much knowledge in calculus). Tnanks man.

[@mohamedabdalla6479]

For me, you are the best one who explained the Fourier transform. After 7 years in the university, I understood the Fourier transform today. Thank you very much

[@iskandarsyahMahmuddin]

what a gem.. this answer everything, you really are the potray of Richard Feynman in describe of master at something

[@plekkchand]

Finally, a proper explanation.

[@Dover0486]

Was able to program it in Excel, and from a constructed signal with three signals superimposed, was able to decompose them using your presentation.

[@jacolansac]

Thanks man, really great video. Straight to the point, answering everything that needed to be answered

[@pworeo625]

Excellent video containing everythink one needs to know about dft at first sight. I didnt find this anywhere else!

[@marcusdalentoft6141]

YES!!!!!!! THIS IS EXACTLY WHAT I NEED!!! 😌😌 thank you so much! i have been struggling so much.

[@KTheXIII]

Holy, that was easier than I thought, thank you so much!

[@michaelsun7968]

Probably the best explanation ive seen

[@johnlaurencechan3035]

The Explanation is so good

[@sfaunl]

This was the best explanation on DFT on KZbin. Thank you.

[@cherma11]

I think I've just watched the greatest video about dft on KZbin. Period! (no pun intended)

[@inventorbrothers7053]

This was very helpful thanks. I spent hours trying to figure this stuff out on my own. Thanks

[@etools]

simply easy understanding expression! very useful. I appreciate you. thank you so much from japanese dsPIC user.

[@greywolf271]

Very very lucid explanation. Wish I had it explained this way in engineering school.

[@GhanashyamSateesh]

Hands down the best video on DFTs... Thank you!!!

[@ThierryPBeaulieu]

Wow! Possibly the best video on DFT on youtube. Thanks!

[@PG-Motorsport]

absolutely amazing. this was much better that the lecture at university

[@alpargur]

purely amazed by the way you explain, reason it. thank you, sir.

[@joho6051]

this is amazing. This has to be the best explanation video about this ever!

[@jacobvandijk6525]

Understanding complexity begins with understanding simplicity. Great example!

[@sau002]

Just this one video was enough for me. Thank you.

[@_mvr_]

holy shit i went through tens of videos trying to get this right. This one was the only true helpful video. Thank you so much.

[@user-ms8km7lh1l]

I'm a computer engineering major and this is super helpful and interesting! thanks!

[@hjen4861]

its not just clear explained...the speaker is also very considerate, human

[@LL-ue3ek]

Best DFT explanations ever. I am very impressed. All details of DFT are presented in ways that are as simple as they are critical. I admit that I had to do enough prior studies for your video to make good sense, but to be able to tie up all the loose ends in people's fractured understandings of DFT and present the subject in such a outstanding way and in its entirety is a rare talent. Thank you again.

[@cazaimi]

The description was as promised, step by step. Thanks a lot!

[@exitmanwei7307]

Thank for your concise and clear explanation, Simon. It's pretty helpful.

[@vegetablebake]

Wow. Brilliant explanation, appreciate all your hard work in making this video.

[@arturro1515]

Best explanation of DFT i have ever seen.

[@kaleevans1692]

About as an amazing explanation as I've ever seen. Great stuff man. Thank you👍🏾

[@ijs8548]

Ahh someone with functional brain finally explain it nice job man.. People need to understand that if i looking for answers on youtube means i no nothing about the subject other idiots just start crashing coplex math till a point i forget the video title

[@madikargin0]

Its one of the best explanation as I ever checked. But last part still a bit blur. With Neurist limit

[@asdfasdf2267]

Thank you good sir, this video solves the missing link in the other 15 DFT videos i've watched.

[@mickshi279]

This video is just pure magic. Thanks for this amazing video.

[@raphaelkriermariani1046]

Finally a video that makes sense! Thanks mate!!!

[@chungnguyen-ql4gs]

Thank you so much! I waited 20 years for your video! :DDDDD

[@jerryjamesmbc]

You make my life too essay... Thank-you very much... None of my teachers explain the actual consent... And thanks again...

[@navjotsingh2251]

Tbh, teachers have a strict time to do all the curriculum. Not saying that's an excuse, but sometimes its just down to you as the student to delve deeper and find the explainations.

[@stevenmackey6346]

Oh my god I wish I could upvote this more than once, excellent video

[@azeiny]

Best ever illustration of FFT. Thanks a lot

[@cookieuk1278]

Wonderful, clear explanation. Many thanks Simon.
