Pls get an HD Camera (it'll help) Reply Jeff Waterman November 22, 2014 huh huh, you said 'hump'. Reply Merly Abondano November 26, 2014 Every periodical signal Reply doublej118jc January 12, 2015 Good presentation, gets to the absolute basics of what an FFT IS. Reply Sam10947 January 26, 2015 not every signal can be represented by bunch of sine waves, only periodic ones Reply Charitha Heshan February 10, 2015 Thanks for the free videos , ignore the idiots who are complaining Reply Devin Akin March 15, 2015 Nice job guys. Thanks for the effort. Reply xxxxxtcxxxxxx March 17, 2015 Very good tutorial. Could have posted with good video resolution. Reply The Guitar Den March 24, 2015 too fast guys. Empathy = ability to understand anothers thoughts. you talking to each other or others who already get it Reply Hype Sounds March 26, 2015 YOU GUYS ARE SO FUNNY! 🙂 Reply Gary 88 April 17, 2015 Awesome vid Reply Rey Cano May 7, 2015 Is that a brass rat I see? #MIT Reply kjake August 17, 2015 @2:50 Not being annoying or anything, but sine typically starts at a value of zero. Reply Mark Ong August 18, 2015 'I used conditioner this morning' Reply Photogolffy September 8, 2015 I like it. Thank! Reply Michi Fuu September 10, 2015 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 🙂 Reply Guillaume Panot September 22, 2015 super guys ! 😉 Reply cantoniosanchez September 23, 2015 This is a description of the discrete fourier transform (DFT). FFT is an implementation. Reply CKCLUTCH October 24, 2015 One stares at the face of the other as the other speaks directly to the cam most of the time. lol Reply Ricardo Saavedra November 5, 2015 I appreciate the effort, but the second guy keeps interrupting the main guy that is talking all the time. So annoying! Reply Munim Anwar November 8, 2015 awesome! Reply PRADYUMAN MEENA November 27, 2015 very well explained Reply q zorn December 9, 2015 supercalifragilisticexpialidocious. thanks. *~) .

Reply moo December 28, 2015 I wish the teachers I have were as interesting and not boring as you guys are Reply abdallah alqassabi January 28, 2016 nice Reply beakf1 January 29, 2016 I thought the video was great and a bit of humor breaks up the boring stuff. Good job lads. Reply Hani Shah February 28, 2016 stop interfering the guy whose explaining. otherwise great stuff. Reply Bon Bon February 29, 2016 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. Reply Jim Moriarty March 7, 2016 I loved it ! Reply Tiberiu Viziru March 24, 2016 Good job guys, you`re explanations are really clear. Reply Роман Василів March 25, 2016 Fft never been so easy thank you very much guys !! Reply Kasraee April 7, 2016 Excellent stuff, Thanks Reply Bilal Syed April 7, 2016 Excelent instructive video Reply OriginalFreeThinker April 7, 2016 Great stuff guys. Thanks for the video. Learned something new today Reply MrNose NZ April 16, 2016 great Tutor !Could you please upload tutorial about how to code FFT on arduino please and arduino coding in general ?Cheers Reply Blair Macdonald April 20, 2016 thank you Reply Rightx line April 26, 2016 Very simple.I wish if my teacher was like you guys. Many thanks Reply Seung Yul Baek May 10, 2016 Thanks guys !! Reply Rich May 18, 2016 Haven't done an FFT since college, but wish you could have been there 20 years ago to explain how they work. Reply pepe6666 October 1, 2016 this is great. its like the world's most awkward fourier transform video. Reply Bằng Bì October 8, 2016 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) Reply Chuck Yeager October 28, 2016 moar pls Reply cobycracker November 12, 2016 thanks. Reply BoogieBass22 December 6, 2016 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. Reply Paul Kafig December 12, 2016 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. Reply Gowtham Sundarrajan December 16, 2016 simple … super …. Reply Filipino Patriot March 4, 2017 Good Tandem. excellent Job guys! Keep Up….Thanks for sharing Reply marcthenarc March 8, 2017 Great video guys. Reply GrimL0gic March 8, 2017 shut up and kiss already! Reply Oskar Zdrojewski March 30, 2017 Useless. This wasn't a tutorial. Reply Bwalya Musanya April 11, 2017 you earned my subscription! 👏👍 Reply Chocolatiste April 30, 2017 That sine turning into a square at 3:00 is pretty much what a tenor sax looks like on fft. Reply Zee Music Company May 3, 2017 Great video, Reply DailyFrankPeter May 12, 2017 Mind blown. I mean it's just maths, but the very fact I understand this kind of maths is mind blowing. Reply parham om May 28, 2017 Why doesn't let this dude hem to explane?!!!! Reply THZ July 20, 2017 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. Reply Suhas Mahesh September 2, 2017 Dude Bro. You amazing!! Reply Richard Smith September 8, 2017 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. Reply They Live September 11, 2017 GAY BROWSKII !!! Reply Phupha Toonkamtoey September 19, 2017 Thanks mate. Reply Reza Arifandie October 6, 2017 i can imagine the left guy playing tomba 2 and says "I would prefer if you can be quiet" to the other guy. Reply Osman Kültür October 12, 2017 Great Vİdeo ! Reply ronald esteban casallas restrepo October 18, 2017 Very good video, many thanks, my question is: this can be done with the Laplace transform ???? Reply Nasseh Khodaie November 14, 2017 Can you FFT that guy's out? The real signal is coming from left. Reply Bob K November 15, 2017 Great overhead tutorial. Thanks guys. This is wonderful for folks like me who want a quick, "What is this?" answer. Reply GamesOnGraphics December 9, 2017 really great video, the interfering is great Reply nader sadeghi December 9, 2017 Great Job! many thanks Reply Jaguar paw December 15, 2017 Guy on the right is a whitless irritating cur Reply tian yang December 17, 2017 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 Reply DrewyJin January 6, 2018 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… Reply Na No January 22, 2018 Fuck this is so interesting if you love to play around with FM synthesizers. Reply Fern Fern March 9, 2018 I didn't expect learning about FFTs to be so funny… I am pleasantly surprised Reply KSCHULTZ824 March 11, 2018 I love you guys Reply chitti yadav March 14, 2018 worest teaching Reply David Wilkie March 30, 2018 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. Reply little sunflower April 5, 2018 "and this isn't just photoshop? this is real?" lol Reply Matt Miller N8QZH April 6, 2018 Great video guys !! Reply misnik1986 April 25, 2018 thanks a lot Reply Aditya Kadam May 10, 2018 Thanks guys 🙂 Reply ZeroZ30o May 30, 2018 I can't believe that it's so good wow Reply Eric Deng June 29, 2018 Helpful! https://www.ebay.com/itm/322691164641 Reply Mashakhetri Sanket Bhagwan ee17m093 July 4, 2018 thanks Reply Tyrrs C July 4, 2018 OMG, second dude is annoying … it only makes it more difficult to understand!

Reply Denise Wallace February 10, 2019 Hilarious and informative! Thanks, guys! Reply LA7YKA Norway February 28, 2019 FFT tutorials are at best with an unfocused camera. Reply Clément Parayre March 26, 2019 thanks Reply Karl Davin March 26, 2019 Surprisingly, the bloke on the right is called Tony, not Dick. Reply Otie Brown April 7, 2019 Well done!Simple, short and clear!Thanks!
