A Set of PDP-12 Programs for Computing Spectra of Power, Coherence, and Phase,

Abstract

A time-varying function may be analyzed for its frequent content by means of either the simple Fourier transformation or the smoothed power density spectrum. Two or more functions may be related through coherence and phase spectra. Working from either analog voltages or previously prepared digital tapes, a set of programs is available for making these computations. Runs have been made with artifically generated pseudo-random numbers, and the results are presented to indicate the sampling variability to be expected under certain conditions. (Author)
