基于LabVIEW平台的AR谱分析技术的实现

Realization of AR power spectrum analysis technology based on LabVIEW

本文介绍了基于LabVIEW虚拟平台的AR谱分析技术的实现。采用最小二乘法,Levinsion算法和Marple算法进行建模．将数据预处理和建模方法利用VisualC++程序编辑器作成动态链接库文件。以LabVIEW软件作为平台,调用动态链接库文件。计算出建模参数以后,利用LabVIEW进行编程．计算AR谱函数．绘制出AR图形。实现AR谱分析技术。

This paper introduces the realization of AR power spectrum analysis technology based on LabVIEW, I adopt the methods of least -squares arithmetic,Levinsion arithmetic and Marple arithmetic to build model,use the editor of VisualC＋＋ to compile data pretreatment process and modeling process to DLL files,The LabVlEW transfers the DLL files. After computing the parameters of model,I programme with LabVlEW to compute the AR power spectrum function, draw an AR graph,carry out the AR power spectrum technique.
