基于AMBE-2000TM的语音通信系统设计
Design of Voice Communication System Based on AMBE-2000TM
【摘要】 介绍了应用AMBE-2000TM声码器芯片设计的语音通信系统的具体实现方案。给出了该语音通信系统中AD73311的模拟前端输入输出接口电路。实验证明声码器在低速率下能获得较好的语音。最后指出了电路设计中应注意的问题。
【Abstract】 This paper introduces the design of a voice communication system based on the AMBE-2000TM vocoder chip.The analog head-end input and output interface circuit of the AD73311 is given.Experiment shows that the voice system can get a superior voice quality in low data rate speech.Some notable issues in circuit design are also pointed out.
