Steve on Image ProcessingDecember 7th, 2009Example of Fourier terminology confusionThis exchange of comments between Cris and me (see comments 11-16) is a good example of the kind of terminology confusion that surrounds Fourier transforms. Cris and I both have a background in signal processing theory, but we were using the term "DFT" to refer to two different transform types, and it took a little while for us to figure that out.3 Responses to “Example of Fourier terminology confusion” |

Steve, I was taught using the same notations you do which is, for my understanding, the standard notations.
I would really love to see a post about the DTFT using Matlab.
Moreover to see the how would you demonstrate the aliasing effect in the spatial domain (Which requires “Sinc” based interpolation).
It’s easy to see the Aliasing in the DFT spectrum yet it’s mostly because of the inherent Aliasing of the DFT and not the sampling in sub Nyquist frequency.
Thanks.
Drazick—Thanks for the suggestion. I plan to show how to demonstrate spatial aliasing.
perfect!
