| 摘 要： | 利用小波对信号去噪,是小波理论应用于实际的一个重要方面。在用由虚拟仪器组成的系统进行测试时,经常要对信号进行去噪、分析等后处理。文中介绍了用于一维检测信号去噪的几种常用方法,并在虚拟仪器开发软件LabVIEW中实现了去噪算法,最后对这几种算法的去噪效果进行了比较。

| Abstract: | Signal de-noising with wavelet is an important application of wavelet analysis.Testing with the measurement system composed of virtual instrument,we should often process the signal with the method of de-noising.This paper introduces several wavelet de-noising methods used in testing one dimension signal.These methods are realized based on the virtual instrument software LabVIEW.The effects of the methods in de-noising are compared. |
