Abstract: CVSD is used in tactical CVSD
Text: CVSD 16 kbps by Atlanta Signal Processors, Inc. Software Overview CVSD continuously-varying-slope delta modulation is a voice-coding algorithm used extensively in tactical communications. Although the speech quality is average, the implementation of the algorithm is simple, allowing for minimal system requirements.
