Description
An Adaptive Differential PCM (ADPCM) transcoder is used to reduce the data rate required to transmit a PCM encoded voice signal while maintaining the voice fidelity and intelligibility of the PCM signal.
Features
- independent of the mode of any previous enables. A transition from short frame to long frame mode or vice versa will cause at least one frame of data to be destroyed. Each of the four sets of I/O pins determines its mode independent of the other sets. Thus the encoder input could be.
