摘　　要：SystemView是一种适用于通信系统设计与仿真分析的软件工具,可以对通信系统的工作过程进行实时仿真分析。为了更深刻地理解AM电台广播系统和AM超外差收音机的工作原理和信号传输过程,本文使用Systemview构建了一个AM电台广播仿真系统,其中接收方采用AM超外差收音机。通过利用SystemView强大的分析工具对传输过程中信号的波形和频谱的进行观测和分析,验证了频分复用和AM超外差收音机的原理,熟悉了AM电台广播系统的通信过程。SystemView is a software which is suitable for simulation and analysis of communication system. It can simulate and analyze the work process of communication system in real time. In order to understand the working principle and signal transfer process of AM broadcast communication system and AM superheterodyne receiver more deeply, we use Systemview to build a simulation system of AM broadcast communication system. Its recipient is AM superheterodyne receiver. By using the strong analysis tools of SystemView to observe and analyze waveforms and spectrums in the signal transfer process, we verify the working principle of frequency division multiplexing and AM superheterodyne receiver, and understand the communication process of AM broadcast system.
