The Discrete Fourier Transform: Sampling the DTFT

The relationship between the discrete Fourier transform (DFT) and the discrete-time Fourier transform (DTFT).

Finally a teacher who could explain this concept CLEARLY. Very very very thanks Mr. Van Veen. Teaching something to someone and comprehending what it is are completely different SKILLS. Not everyone should be allowed to be teacher! Thanks again sir!

Very well explained! Reading that same topic from a book for hours couldnt solve my problems. Now i got it! Thank you!

Pretty amusing when you google something about a class, only to find a youtube video from your professor.

this is one of the best videos on YouTube.thanks man

You cats are on the right groove with compression, there could be some amazing discoveries there.

I love how he goes all in on the owners and chefs but always stays respectful towards the wait

Ole Samir Kaddoura talked about this at Montverde, and Eddie Leibler, Hector Montalban chimed in too.

I was wondering why your name looked so familiar. then i realized i own a copy of the first editions of your book. too cool.

You gave me confidence in this topic. Thanks!

Correct me if I'm wrong, but I believe JPEG usues DCT, not DFT

Thank you!!! This is awesome, I just found you and you have saved my semester. Eres mi puuto Mario Castroo de PDS!

At 14:28 Xs[k] <-> (IDFT) is Xs(n) it is written DFT

[npnike]

Why is it okay to sample the frequency as 2*pi*k/N? Because then since k<=N-1, frequency is less than 2*pi and so we are missing out on every other frequency over 2*pi.

[avinasha]

At 12:49 X(e^jw) S(e^jw) IDTFT is x(n) * s(n) it is written DTFT

[sameermalik]

great service to students sir...continue the good work

[josevillegas]

Hello Barry, can you direct me to where you show that DTFT'{impulse train} = impulse train? 

[masoudy]

goddd, tnx man, this helped in so many ways!!! ❤❤❤

[allsignalprocessing]

I can try if you tell me a time in the video and an equation. I'm not sure what you are referring to exactly.

[francescoesco]

That's exactly what I was looking for!! Thank you so much =D

[bhuvi]

This is exactly what I wanted ! Thank you :)
