Abstract
Base station equipment of a digital mobile communication system includes a digital audio signal processing apparatus provided for each message channel for low bit rate coding and decoding a digital audio signal. Each digital audio signal processing apparatus includes a plurality of memories that store a plurality of low bit rate coding/decoding programs differing from each other to comply with different low bit rate coding/decoding methods. A system control circuit determines the low bit rate coding/decoding method of an applied digital signal for controlling a selector to select a memory that stores the corresponding low bit rate coding/decoding program. As a result, the digital audio signal processing apparatus perform digital to digital conversion of the applied digital signal according to the low bit rate coding/decoding program stored in the selected memory.
