OrCAD16.3在通信电子线路教学中的应用

Application of OrCAD16.3 in Communication Electronic Circuit Teaching

采用OrCAD16.3软件对AM信号、DSB信号、包络检波器、同步检波器进行建模并仿真,观察到调制解调输出波形,改变参数的值,可观察到恢复出来调制信号失真,验证包络检波器和同步检波器的检波条件。

This paper completed modeling and simulation of AM, DSB, envelope detector, synchronous detector using OrCAD16.3, the waveforms of modulation and demodulation can be observed, changing the values of parameters, the modulation signal distortion can be observed, which verify the detection conditions of envelope detector and synchronous detector.
