We will derive spectral representations for them just as we did for aperiodic CT signals. WebThe discrete time Fourier transform (DTFT) is the member of the Fourier transform family that operates on aperiodic, discrete signals. The best way to understand the DTFT is how it relates to the DFT. To start, imagine that you acquire an N sample signal, and want to find its frequency spectrum. cloud computing: an overview
