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.Keywords
