摘要

基于 LabVIEW 设计了集电信号的傅里叶分解、合成、频率响应及频谱分析功能于一体的虚拟仿真实验系统。该软件具有图形用户界面，可调节信号类型、幅度、频率和电阻、电容、电感等各种电路参数。测试结果表明该实验系统不仅能实现电路实验箱全部功能，还能实现频率响应、频谱分析及改变电感进行傅里叶分解等实验箱不具备的功能。在实验教学中，将开发的虚拟仿真实验程序放到网上，用于疫情期间的线上教学，能有效地提高电路实验教学质量。

Abstract:

Based on the design of graphics program language of LabVIEW, a platform of virtual simulationexperiment for Fourier progressional dissolution and compostion of periodic signals and the amplitude-frequencycharacteritic of the RLC circuit, and frequency domain analysis is developed.The simulation software has agraphic user interface where different experimental parameters such as various types of electrical signals andelectronic components are provided for users to adjust. The experimental results show that this simulationsoftware not only realize all functions of the actual circuit experiment box ,but also realize frequence response.spectrum analysis and electrical signal decomposition by changing induence.ln the experiment teaching,thesharing of this visual simulation experiment on the network for online teaching,which is useful for the quality ofstudents’pre-class preview improve the teaching quality effectively.

Key words: LabVlEW visual instrumentation informationized teaching
