基于LabVIEW相关分析的研究

Research on LabVIEW-based Correlation Analysis

利用LabVIEW的Analyze Signal Processing Time Domain函数模板提供的Auto Correlation和Cross Cor-relation函数构建了相关分析的虚拟仪器,对LabVIEW的相关函数进行了修正,并通过典型的信号对该分析仪进行仿真试验。通过LabVIEW建立虚拟仪器使复杂抽象的相关理论的学习和分析变得直观形象,为信号分析和处理的研究和学习找到了简便、快捷、经济的方法。

This paper presents an algorithm of correlation analysis and its application in LabVIEW. By using the function palette provided by Analyze Signal Processing Time Domain in LabVIEW and the.function of cross correlation, a virtual instrument is set up to modify functions related to LabVIEW, to conduct simulation experiments through typical signals. The establishment of virtual instrument through LabVIEW simplifies and visualizes the analysis and the study of abstract and complex theory, which in turn provides a more convenient, quicker and more economical method to the research on the analysis and processing of signals.
