摘　　要：传统仪器下的高校实验教学,已严重滞后于信息时代和工程实际的需要。运用虚拟仪器代替传统仪器,不但能满足电子信息类实验教学的需要,降低实验室成本,用户还可以根据自己需要定义仪器的新功能。本文主要设计了基于虚拟仪器的实验教学系统,采用模块化的设计思想,利用LabVIEW开发平台给出了低通滤波器实验、典型信号频谱分析实验、自相关实验、实验数据线性拟合实验的前面板图和程序流程图,这些实验构成一个虚拟实验教学系统。The high school experiment teaching with traditional instruments is slow to demands of information ages and real engineering.When traditional instrument was replaced by virtual instruments,it would satisfy the experiment teaching of electronic information,cut down the experiment set-up budget.What is more,user could define new capability of instrument according his own demands.In this paper,the experimental teaching system based on the virtual instrument is designed,which used the concept of modular design,and it gave the front board plans and procedures flow chart of a low-pass filter experiments,the typical signal spectrum analysis of the experiment,the relevant experiments,linear fitting of experimental data by LabVIEW development platform.These experiments constituted a virtual experiment teaching system.
