Abstract

In this paper, Adaptive Non-uniform Sampling Delta Modulation (ANS-DM), a modification of the non-uniform sampling delta modulation technique, is proposed and examined. The proposed technique has been applied to audio and image processing; simulation results have shown that the ANS-DM technique has good improvement over LDM, ADM and NS-DM on the compression ratio, the SQNR, and the dynamic range.
