Z & Fourier Transform Relationships

[nippie96]

If I understand your video, I guess a more correct explanation would be:

- the xy-axes are the domain of the Z-transform

- the gray surface is the Z-transform of some function

- the red line is the Fourier transform of the same function.

- the green cylinder shows that the domain of the Fourier transform is the unit circle on the complex plane

...please correct me if I am wrong.

@nippie96 That's exactly right. Thanks.
