摘　　要：介绍音频信号数字通信实验装置设计的实现过程,该装置以FPGA为主控芯片,以光纤为通讯媒介,将音频信号数字化后通过光纤实现传输,并对电路各个模块的功能及实现加以说明。实验装置采用分模块式的设计,设计思路灵活,结构清晰。电路在Altium Designer和Protel99中设计完成,并且在QuartusⅡ环境下用VerilogHDL语言进行编程并对程序进行仿真。该装置已做成了实体,可以实现音频信号的发射与接收,达到设计提出的要求。The audio signal digital communication device design process is introduced. The experiment device is controlled by FPGA and transferred by optical,which explains that audio signal can be conveyed after digitization. Also ,the function and the realization of each module circuit have been stated. The device is designed by building blocks ,making it flexible and structuring to realize. The circuit is designed and finished in Altium Designer and Prote199,whieh also has been programmed with VerilogHDL language and simulated in Quartus II .The set has been realized and can send or receive audio signal successfully. Proved to meet requirements raised by designer.
