摘要
介绍了一种小型通信系统的设计方法及其工作原理。系统中的发射机单元采用调频方式实现音频信号的调制而接收机单元对调频信号进行解调 。
This paper introduces a method of designing a small communication system as well as its work principle. In the emitting part of the system, the audio frequency signal is modulated through frequency modulation while the receiving part restores the primitive audio frequency signal.
