Discrete Time Fourier Transform (DTFT) vs Discrete Fourier

WebCreated Date: 9/12/1998 11:46:07 PM WebThe spectrum of the DTFT is continuous, so either f or ω can be used. The common choice is ω, because it makes the equations shorter by eliminating the always present factor of 2π. Remember, when ω is used, the frequency spectrum extends from 0 to π, which corresponds to DC to one-half of the sampling rate.
