THE EQUALITY OF QUANTIZATION WITH DITHER SIGNAL AND OVERSAMPLING FROM THE POINT OF VIEW OF THE CRITERION OF SNR

Anna Domańska

Abstract

SNR is a characteristic of analog-to-digital (A/D) conversion. One of its applications is the valuation of the “effect” of the change of the resolution of A/D conversion. SNR may be improved by modifying the process of discretization in terms of time (sampling) and value (quantization).<br />The present article discusses the equality of these two types of modification from the point of view of the criterion of SNR.
