摘要
本文讨论了用单片微机对移动通讯系统(移动无线电话系统)采用DTMF信令实现系统控制(准确接线、拆线)、信令处理(调制解调)及监控的方法。
This paper disscusses single-ship microcomputer control system application on mobile communication (mobile automatic radiophone)and applies dual tone multi-frequency signal-order to realize system control (authorization connect lines or dismantles lines),process signals-order (modulate-demodulate) and monitor.
