G: The Fourier Transform of a Periodic Function
Barbara Burke Hubbard
Open publisher page 0 citations
Abstract
As T becomes longer, the coefficients are spaced closer and closer together. When T = co, our periodic function has become nonperiodic, and the discrete Fourier series has become a continuous Fourier transform; we are looking at all possible frequencies. (Of course, in practice a Fourier transform is computed for some sampling of frequencies, as described in The Fast Fourier Transform, p. 141.)
