APPROXIMATE METHODS OF SIMULATING RANDOM NOISE WITH PURE TONE SOURCES

Abstract

The problem of the approximation of a given random signal with modulated pure tone signals is studied from the standpoint of approximation of the power spectrum. The equal energy and moment matching techniques are developed for the selections of the modulation parameters of the pure tone sources. Techniques are developed for the selection of parameters of a switched pure tone source. The power spectrum is also approximated by a rational polynomial scheme, which uses a minimax procedure, developed in the appendices, for selection of pure tone operating parameters. Several examples of each of these techniques are given.
