摘要
本文介绍一种可用于多种电话交换机的高精密度数字多频收发码系统。该系统以数字信号处理器作为主控部件 ,用数字频率生成方法产生多频信号加以发送 ,用数字滤波方法完成多频信号的接收和译码。文中着重介绍系统硬件和软件的设计特色。
The paper relates to a high accuracy digital MF sender /receiver system for various telephone switching systems.By using a DSP as the main controller,the transmitted MF signals are produced with digital frequency generation method,and the receiving and decoding of MF signals are performed by a digital filter.The features of system hardware and software design are emphasized.
