摘要
该设计在保证传送话音质量的基础上,采用AMBE_2000TM芯片对语音信号进行数字化压缩,应用动态时分复用等技术实现了装备间的数话同传。并给出了A/D,D/A转换电路、语音编解码芯片及单片机的电路设计。其基本保证了数话同传、语音信息和数据信息流畅;语音通话质量高,缩短了武器系统的作战反应时间,提高了武器装备作战性能。
In this design, to ensure the quality of speech transmission, digital compression for speech signal by using AMBE - 2000TM , data- speech transmission between equipments is realized by dynamic time division multiplex teihnology. The circuit design of A/D,D/A conversion,speech compression chip and single chip computer are given. It ensures smoothless of data - speech transmission, speech information and data information, a high quality reduces the response time and improves the performance of combat weapons and equipment.
