A Different Approach to Quantizing Noise Analysis in Delta Modulators,

摘要

A new approach for determining quantizing noise in delta modulators has been developed. This approach has been applied to the delta modulation of first order Markov sources. The analysis technique avoids the necessity of dichotomizing quantizing noise into slope overload and granular components,and working with them independently. Formulae,which can be evaluated numerically,are developed for quantizing noise probability density functions and power spectra. Computer solutions are presented and compared with previous simulation results. Generalization of the method to Differential Pulse Code Modulation systems is discussed. (Author)
