| Abstract: | Digital Voice Systems Inc.'s AMBE 1000 vocoder chip is a high performance, full duplex, real time speech compression coder chip. It can be used in many fields such as satellite communication, security communication, video conferencing etc.. First, A/D D/A interface and channel interface principles are introduced briefly in the paper. Second, to design a practical voice communication system, the design method of A/D D/A interface circuit between AMBE 1000 and MC14LC5480 PCM coder, and channel interface circuit between AMBE 1000 and AT89C51 microcontroller is given in detail. Some notable problems in circuit design are pointed out. |
