Abstract
In chapter 2, a number of techniques for efficiently coding the speech signal at bit-rates down to about 16 kbits/s were described. These included log-PCM, adaptive PCM (APCM), differential PCM (ADPCM), delta modulation (DM), adaptive delta modulation (ADM) and continuously variable slope delta modulation (CVSD). All of these techniques operate directly on the time-domain signal and achieve reduced bit-rates by exploiting the sample-to-sample correlation or redundancy in the speech signal.
