Abstract : This report presents FORTRAN IV source program listings for 8 routines of general use in power spectral density analyses on a digital computer. Included are a Fast Fourier Transform (FFT) routine, power density function routine via the FFT, and data massaging routines. Mathematical derivations and manipulative techniques of deterministic spectral analysis theory for sampled data are set forth in detail. (Author)
