摘要
提出了利用集成电路实现多频互控信号的同步接收方法，分析了系统呼损概率大小，给出了主要电原理图和实验结果．结果表明，在输入信号幅度不小于－４０ｄＢ的条件下，系统工作可靠．
A method of synchronous receiving for MFC signal using integrated circuits is raised. A call cost probability was analysed. The principal circuit diagrams and test results are given.The tests show that the system can operate reliably if the amplitude of input signal is greater than - 40dB.
