摘　　要：文章针对"通信电子线路"实验教学中硬件实验的缺点,以幅度调制和解调为例,提出将LabVIEW中图形编程语言(G语言)用于"通信电子线路"实验,并给出了虚拟仪器前面板的构成形式和虚拟实验的程序框图。通过实例说明采用LabVIEW软件对"通信电子线路"实验进行仿真与性能分析,可以改善实验条件和效果。In order to overcome the shortcoming of hardware experiment in the communication electronic circuit experiment teaching, the method of using graph programming language （G language） of LabVIEW in experiment is put forward. In this paper, the experiment ideas of amplitude modulation and demodulation are discussed chiefly. In addition, the block diagram of virtual experiment and panel of virtual instruments are provided. The experiments illustrate that communication electronic circuit can be simulated and analyzed by LabVIEW software, which makes progress in condition and effect of experiment.
