WebExact periodicity over N samples of interest is rarely the case in practical applications and most real-world signals are better represented in a stochastic sense than with assumptions of exact periodicity over any given set of samples. Web1 It's periodic for sampled signals. As for intuition as to why, just look to aliasing. – AnonSubmitter85 Mar 24, 2014 at 18:06 Add a comment 1 Answer Sorted by: 0 Your time signal consists of a number of samples in a limited time interval. The Fourier transform approximates that signal with a set of sines and cosines.
