振幅调制解调系统的System View实现

Realization of Amplitude Modulation and Demodulation system Based on System View

在模拟调制中,振幅调制(AM)是所有线性调制的基础,因此在模拟通信中占有非常重要的位置。本文运用System View软件这一强有力的动态分析工具,建立了可视化的AM通信系统模型,介绍了AM系统的工作原理、AM信号的产生和解调方法,分析了AM信号的频谱特性。

Amplitude Modulation is the base of all kinds of linear modulation,so it plays a very important role in the field of analog communications.ln this paperAased on the powerful dynamic analysis software SystemView.the visual model of AM communication system is established;its operation principle and the methods of amplitude modulation and demodulation are introduced.And the spectrum characteristics of AM signals are analyzed.
