摘要
介绍了AMBE-2000TM声码器语音压缩解压芯片的工作原理及其应用;给出了语音通信系统中AMBE-2000TM与PCM编解码器AD73311的A/D-D/A接口电路。该系统可以在低速率下保持声音自然、语音清晰,并且在选择语音速率和误码率中提供了很高的灵活性,能实现全双工、实时语音压缩解压等功能,此外还具有低成本、低功耗等优点。因此在卫星通信、数字移动通信、保密通信、语音邮件等方面都有广泛的应用。
The paper introduces the working principle of AMBE-2000^TM sounder pronunciation compression decompression chip and its application; gives the connection electric circuit in the pronunciation communications system AMBE-2000^TM and PCM codec encoder-decoder AD73311 A/D-D/A. This system may keep the natural sound, clear pronunciation under the low gear rate, and it is very flexible in the pronunciation speed and the error rate choosing with the functions of full-duplex and real-time pronunciation compression decompression, in addition also has the advantages of low cost, low power loss. Therefore it is widely used in the aspects of satellite commurication, numeral mobile communication, privacy communication and pronunciation mail.
