Abstract :
This paper gives a sufficient condition on the average rate of quantizer step size adaptation rate that preserves adaptive differential pulse code modulated (ADPCM) stability under the assumption that the predictor is nonadaptive. The result appeals to some new developments in the passivity analysis of linear time varying systems
