The title is misleading. This video has nothing to do with FFT (which is a particular algorithm of calculating the Discrete Fourier Transform quickly), but with its application to show the spectrum of a signal. The video shows how to view the spectrum on an oscilloscope, not how to do the FFT algorithm.

THIS is how you teach engineering. I'm actually motivated to learn now. A lot of professors just lecture in the wrong way… Thanks Tektronix. You've earned a like and subscribe.

OK video, but the title is misleading. You've explained the difference between a time and frequency signal domain and why it's useful. An FFT is an algorithm for calculating a DFT. Please consider changing the title of your video. Thanks.

thanks guys! but imho you explained the ordinary fourier transformation and not the fast fourier transformation which is fast, because of some – for me – unkown symmetry. i was looking for an explanation for this.

The explanation was great for explaining how to transform FFT back into the original signal, but not so much on transforming the waveform into FFT, as far as the math is concerned.

Nice Videos. Pls get an HD Camera (it'll help)

huh huh, you said 'hump'.

Every periodical signal

Good presentation, gets to the absolute basics of what an FFT IS.

not every signal can be represented by bunch of sine waves, only periodic ones

Thanks for the free videos , ignore the idiots who are complaining

Nice job guys. Thanks for the effort.

Very good tutorial. Could have posted with good video resolution.

too fast guys. Empathy = ability to understand anothers thoughts. you talking to each other or others who already get it

YOU GUYS ARE SO FUNNY! 🙂

Awesome vid

Is that a brass rat I see? #MIT

@2:50 Not being annoying or anything, but sine typically starts at a value of zero.

'I used conditioner this morning'

I like it. Thank!

Saved my life today. Jaja someone said ancient devices jajaja but those are exactly like the ones at my faculty so you really saved me 🙂

super guys ! 😉

This is a description of the discrete fourier transform (DFT). FFT is an implementation.

One stares at the face of the other as the other speaks directly to the cam most of the time. lol

I appreciate the effort, but the second guy keeps interrupting the main guy that is talking all the time. So annoying!

awesome!

very well explained

supercalifragilisticexpialidocious. thanks. *~) .

homo sapiens tutorial

Thanks so much! great job and really helpful!

I wish the teachers I have were as interesting and not boring as you guys are

nice

I thought the video was great and a bit of humor breaks up the boring stuff. Good job lads.

stop interfering the guy whose explaining. otherwise great stuff.

I loved it !

Good job guys, you`re explanations are really clear.

Fft never been so easy thank you very much guys !!

Excellent stuff,

Thanks

Excelent instructive video

Great stuff guys. Thanks for the video. Learned something new today

great Tutor !

Could you please upload tutorial about how to code FFT on arduino please and arduino coding in general ?

Cheers

thank you

Very simple.I wish if my teacher was like you guys.

Many thanks

Thanks guys !!

Haven't done an FFT since college, but wish you could have been there 20 years ago to explain how they work.

this is great. its like the world's most awkward fourier transform video.

dear, i have a question for u. output of the iFFT process, is it modulated signal with high frequency? because i see it is multied with e^(-2piFt)

moar pls

thanks.

simple … super ….

Good Tandem. excellent Job guys! Keep Up….Thanks for sharing

Great video guys.

shut up and kiss already!

Useless. This wasn't a tutorial.

you earned my subscription! 👏👍

That sine turning into a square at 3:00 is pretty much what a tenor sax looks like on fft.

Great video,

Mind blown. I mean it's

justmaths, but the very fact I understand this kind of maths is mind blowing.Why doesn't let this dude hem to explane?!!!!

thanks guys! but imho you explained the ordinary fourier transformation and not the

fastfourier transformation which is fast, because of some – for me – unkown symmetry. i was looking for an explanation for this.Dude Bro. You amazing!!

GAY BROWSKII !!!

Thanks mate.

i can imagine the left guy playing tomba 2 and says "I would prefer if you can be quiet" to the other guy.

Great Vİdeo !

Very good video, many thanks, my question is: this can be done with the Laplace transform ????

Can you FFT that guy's out? The real signal is coming from left.

Great overhead tutorial. Thanks guys. This is wonderful for folks like me who want a quick, "What is this?" answer.

really great video, the interfering is great

Great Job! many thanks

Guy on the right is a whitless irritating cur

没听懂英文，大概明白啥意思：应该是说矩形波可以是由很多种频率的波合成的，越接近矩形波频率的波的频率分量越大， 它们的频率能量是一个向下的曲线

Guy on the right. ***king annoying. Keeps wanting attention. Get off… Let the Left man do the explaination. You just take the cards away pls…

Fuck this is so interesting if you love to play around with FM synthesizers.

I didn't expect learning about FFTs to be so funny… I am pleasantly surprised

I love you guys

worest teaching

Good demo of what a practical device does, it's in the "real" world, directly related to basic elements of material existence.

Can this simple technical identification of phenomena be scaled to extended to the Quantum Fields Mechanism in Chemistry and Physics.

"and this isn't just photoshop? this is real?" lol

Great video guys !!

thanks a lot

Thanks guys 🙂

I can't believe that it's so good wow

Helpful! https://www.ebay.com/itm/322691164641

thanks

OMG, second dude is annoying … it only makes it more difficult to understand!

"You sure know your way around an oscilloscope" … otherwise good explanation!

the left dude kept it interesting!

Where I could read open Audio processing journals?

👍👍👍

crazy drawing skillz

Both dudes were on point. Fun and informative, great job!

Hilarious and informative! Thanks, guys!

FFT tutorials are at best with an unfocused camera.

thanks

Surprisingly, the bloke on the right is called Tony, not Dick.

Well done!

Simple, short and clear!

Thanks!

GooD

7 years later this is still an amazingly cool (in a way only nerds would understand) video.

Very good presentation guys..Thanks 🙂

can someone give the right guy a high five on the face
