FINITE FOURIER TRANSFORM THEORY AND ITS APPLICATION TO THE COMPUTATION OF CONVOLUTIONS, CORRELATIONS, AND SPECTRA
Douglas W. McCowan · 1966
Abstract : The theory of finite Fourier transforms is developed from the definitions of infinite transforms and applied to the computation of convolutions, correlations, and power spectra. Detailed procedures for these computations are given, including listings and writeups of FORTRAN subroutines.
