摘要
设计了一种简单而实用的小型音频交换系统电路,它采用AT89S52单片机作为主控单元;采用MT8816AE作为交换控制矩阵。单片机通过接收主控计算机发送的通信帧来控制矩阵开关工作,从而实现了终端语音交换。
A simple,useful and small audio switching system is designed in this paper,which uses AT89S52 as the main control unit and MT8816AE as the switch of control matrix.MCU is the master of the matrix switch by receiving the frame which is sent by the main master computer.This system can accomplish audio switching among every communication terminal.
