摘要
使用光纤发射机进行语音通信可以开发具有极高抗干扰能力的新产品。介绍了语音光纤发射机的结构设计原理,提出了设计的方法,并给出了以语音编码芯片AD74111和发光器件HFBR-1414为核心芯片的电路设计过程。设计实例适合用于工作环境复杂的语音通信系统。
New products with high performance of noise immunity can be designed using fiber-optic transmitter to complete audio communications. Principles of the construction and designing methods of audio fiber-optic transmitter are presented in this paper, and the progress of designing a digital audio fiber-optic transmitter which takes the audio codec AD74111 and light-emitting diode HFBR-1414 as the core chip is also discussed. System designed in this paper is suitable for use in audio communication systems which work in easy interfered conditions.
