The Realization Method of Multi-channel All-digital CVSD Codec
CVSD (Continuously Variable Slope Delta Modulation) speech encoder was widely used in the military communication system. This article has analyzed a all digital CVSD encoder and decoder algorithm between CVSD and PCM signal; has studied and simulated the integral circuit and ellipse filter; has put forward a new realization method of multi-channel encoder and decoder with digital circuits, has described the working mechanism of sub modules and analyzed the consuming of resources. Compared with the traditional method using A/D, this method is simple and easy for multi-channel processing.
