一种AM调幅-2FSK调频通信系统的研究

Study on AM-2FSK Modulation Communication System

摘要:

介绍了AM(standard amplitude modulation)和2FSK(binary frequency-shift keying)的基本原理，提出了把二者结合起来的双重调制技术用于同时进行语音和数据的无线传输。在接收端用AM接收机解调AM语音信号，用内加的MC3362解调FM数据信号，达到了二媒体同时通信的目的。

Abstract:

In this article,the principle of AM(standard amplitude modulation)and 2FSK(binary frequency-shift keying)are first introduced.Then a technique of dual modulation combining AM and 2FSK is proposed for simultaneous audio and data wireless transmission.At th
