Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | А simple and complete analysis of nonuniform scalar quantizers based on the companding technique, so-called compandors, is presented. The performance of the scalar compandors for different definition of compressor functions are considered and compared with the performance of optimal Lloyd-Max’s scalar quantizers. There are several definitions of compressor functions. Two of them, that are functions of the support region of the compandor, are presented in this paper. The support region of the compandor is defined with the maximum amplitude of the input signal that enables optimal compandor’s load. In order to design the scalar compandor having the best performances i.e. with the smallest distortion, it is necessary to determine optimally its support region. |
