Abstract :
Differential PCM with backward adaptive prediction (DPCM-APB) is a popular technique for data compression. Because of the presence of the quantizer in the feedback loop the adaptation process has been difficult to analyze. In this paper we present a bound on the predictor misadjustment and obtain some easily verifiable conditions for convergence of the bound.
