Description

This report discusses 32-kbit/s Adaptive Differential Pulse Code Modulation (ADPCM) transcoders. A half-duplex ADPCM transcoder which complies with the CCITT recommendation (G.721) can be achieved with a single TMS32010. If the transcoder is used only for private lines a full duplex non-CCITT ADPCM transcoder is more cost-effective and can be designed with a single TMS32010 processor. Both the
