EFFECTS OF NON-UNIFORM SAMPLING AND LIMITING ON CORRELATION FUNCTIONS

Abstract

The thesis is a study of nonuniform block sampling theory and its application to the study of correlation functions of sampled signals. The research evolved from the specific problem of reducing the odd harmonic terms that appear in the correlation function of hard-limited and uniformly sampled sinusoidal signals. These odd harmonic terms arise because of the synchronism between the periodicity of the uniform samples and the periodicity of the odd signal harmonics produced by hard limiting. Nonuniform sampling is used to reduce the periodicity effects and, thus, to reduce the odd harmonic terms in the correlation function. With block sampling, the odd-harmonic correlation- function responses resulting from clipping and sampling can be reduced by any desired degree by the proper choice of sampling parameters.
