Telemetry Standards. Chapter 5: Digitized Audio Telemetry Standard

Abstract

This chapter defines continuously variable slope delta (CVSD) modulation as the standard for digitizing audio and addresses the method of inserting CVSD encoded audio into a pulse code modulation (PCM) stream. Additional information and recommendations are provided in Appendix 5-A, which was extracted from the applicable sections of Military Standard 188-113, which has been canceled with no replacement. Additional information regarding the insertion of the digitized voice signal into a PCM frame may be obtained in the documentation of US Patent 5,557,635.
