基于LabVIEW技术的模拟电路实验的设计.doc

摘要
虚拟仪器是当今仪器技术发展的重点,LabVIEW是一种图形化编程语言,作为数据采集和仪器控制软件的标准被广泛性应用于工业界、研究性课题。
论文主要研究基于LabVIEW的模拟电路实验系统的设计,设计过程中的虚拟积分微分器采用图形化编程语言LabVIEW进行设计,通过各种波形信号的输入,对其各种参数进行设置,然后利用信号选择器选择所要输入的信号,然后经过程序的处理之后在前面板上显示积分微分前后的变化,在波形图中显示输入输出信号的波形,观察虚拟积分微分器的结果,得出结果与理论分析的结论是一致的。设计的积分微分器能对正弦波、方波、三角波等波形进行正确显示和积分微分处理。

The Design of Analog Circuit Experiment System
Based on LabVIEW
ABSTRACT
Virtual instrument is the instrument technology development focus, LabVIEW is a graphical programming language, as data acquisition and instrument control software is widely used in industry, academia, research topic .
The paper mainly studies the design of analog circuit based on LabVIEW, and the design process of virtual differential device uses the graphical programming language LabVIEW, through various waveform signal input, and set various parameters, use a signal selector to select the input signal, through the process of treatment in the front panel display integral and differential change in the waveform display, and display the input and output signal on the waveform graph, analyze the virtual integral differential actuator result, the result mon with the conclusion of the theoretical analysis. In this paper, the design of integral differential device capable of sine wave, square wave, triangle wave, waveform display correctly and differential treatment.
