Journal: ELECTRONIC MEASUREMENT TECHNOLOGY

Keyword:  Multisim调制解调频谱分析;
Abstract: 调制和解调是通信技术的核心.鉴于Multisim分析高频电路的优点,在深入分析双边带幅度调制和解调的基础上,本文在Multisim环境下建立了一个通信系统模型.通信系统模型利用磁场感应,采用变压器模块实现天线的收发功能;采用放大器对解调信号进行放大,实现对输入信号的再现;利用Muhisim提供的示波器模块和频谱分析模块,分别对调幅波和解调波进行了波形和频谱分析.实验结果表明,Muhisim在高频电路仿真中具有快速、准确、灵活等优点.
