Recommended Modifications to Improve CVSD Speech-Encoding Performance.
Morris,Joel M · Defense Technical Information Center (DTIC) · 1977
This report contains a discussion of several continuously-variable-slope delta modulator (CVSD) modifications warranting theoretical and experimental evaluation as performance-improving techniques. These candidate techniques were derived from a survey of the applicable research literature on delta modulation (delta) M and other waveform encoding methods. The report begins with brief background information on low-data-rate speech encoding, delta modulation, and CVSD.
