Discrete Fourier Transform Circular Convolution Property

The convolution-multiplication property of the DFT, circular convolution, and zero padding to recover linear convolution from circular convolution.

Seing it visualy helped me understand both the circular convolution and the value you have to give to N to recover the original signal. Thanks a lot!

Woahhh amazed and excited to study dsp the next year. Came out of interest while studying my signals course. Also appreciate the aliasing happening in the y tilde n when N is less than the DFT length.

I think there is a mistake at 1:28 where there lacks a minus and it should be e^(-j2pikm/N)

[ccuuttww]

2:27 can someone explain how the pink bracket happen there

[SmoothChino]

its hard to keep track of what you are pointing at when you are explaining.

Good video! Very clear and easy to understand! Thank you!

[CasperBHansen]

Your videos are generally great, but all of the small aside notes you make, which stops what you're doing in derivations, make it really difficult to follow along. If some of those small details are used, start the sentence with "remember that..." and then lead with "therefore" — it would make all the difference.

Great explanation! Thank you very much!

[rgsuki]

You gave great explanation, but the example really does not help.
