发明名称 CVSD Transmission with improved intelligibility of voice signals
摘要 Voice signals subjected to differential modulation such as CVSD modulation are made more intelligible by differentiating an electrical analog of the voice signal, clipping peaks of the differentiated signal, integrating the clipped differentiated signal, and applying the integrated signal to a differential modulator such as a CVSD modulator.
