Abstract
We describe an adaptive differential PCM (ADPCM) coder which makes instantaneous exponential changes of quantizer step-size. The coder includes a simple first-order predictor and a time-invariant, minimally complex adaptation strategy. Step-size mult...This publication has 2 references indexed in Scilit:
