摘要
虚拟仪器(VirtualInstrument,简称VI)代表着目前测试仪器领域的发展方向,LabVIEW语言是一种功能强大的虚拟仪器开发平台;小波变换是信号分析处理的一种重要方法。本文旨在对LabVIEW进行二次开发,拓展其小波分析和小波包分析功能,将其应用于对非平稳信号的消噪处理。
Virtual instrument has taken the lead of the profession of test instrument. LabVIEW is a kind of developing flat of virtual instrument with powerful function.Wavelet transform is an important way to study signal in time-frequency domain.The main content of the paper is to put up the 2nd development of LabVIEW, enlarge the analytic function of wavelet and wavelet packet , make use of them to deal with nonstationary random signal, and compare wavelet analysis with traditional Fourier transform.
