In signal processing and related disciplines, aliasing refers to an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled.

Why does the frequency sampling method for FIR filter design operate in this manner?
If I only sample the frequency response, the time domain signal will be periodic with some aliasing. (does the DTFT works also this way? so sampling in frequency equals periodization in time?) … Now I can also apply any windowing function to the filter coefficients to partially get rid of that aliasing and improve the filter response
Does it makes any sense? …

Why does the frequency sampling method for FIR filter design operate in this manner?
Since the sinc() function is not limited in time should I get some aliasing in the time domain while sampling the frequency response? …
