| 摘 要： | 介绍了用单片机实现数据采集,LabVIEW作为开发平台实现数据通信,并利用LabVIEW实现数字信号频谱分析虚拟仪器的方法.频谱分析过程中,将两个不同频率的正弦信号叠加后再叠加上白噪声,通过虚拟频谱分析仪,可以有效的分析出原始信号.通过对用VB开发的系统与用LabVIEW开发的系统的比较,突显出LabVIEW的优势.

| Abstract: | The paper introduces a method of design employing the microcomputer to acquire the signal and the LabVIEW as the design platform to realize the communication between the microcomputer and the PC.The LabVIEW is adopted to realize the spectrum analysis visual instrument.Through the process of spectrum analysis,two different frequency sine signals are added together and then added with the white noise.The result is input to the spectrum analyzer,the original signal is analysed.By comparing the system designed by the VB and the system designed by the LabVIEW,we can easily see the advantage of the software LabVIEW. |
