摘要
本论文主要研究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环境中实现了上述去噪算法,最后对这几种算法的去噪效果、信噪比、均方误差和计算时间等方面进行了比较,同时也就小波基函数的选择对去噪效果的影响进行了比较分析。
This paper mainly study some methods of de-noising on testing signal in common. And these methods of de-noising are realized by LabVIEW. Finally we analyze the effect of de-noising, SNR, RMS and operating time corresponding these methods. At the same time we compare and analyze the effect of de-noising with choosing different wavelets.
