Title :
Sampling bandlimited periodic signals-an application of the DFT
Author :
Brown, John L., Jr.
Abstract :
It is shown that Cahn´s representation for bandlimited periodic signals in terms of their sampled values can be derived simply by using the discrete Fourier transform (DFT). Parseval´s theorem for the DFT allows the average power of such a signal to be expressed directly in terms of signal samples without harmonic analysis.
