化学信号滤波的小波新技术

New Wavelet Filtering Technique of Chemical Signals

提出了一种基于墨西哥帽小波的信号滤波的新方法———MWDA。它是一种化学计量学技术 ,易于操作 ,被成功地应用到分析化学信号的处理中。MWDA即使处理信噪比为 1的高噪音信号 ,仍能获得满意的结果。

A new filtering method MWDA in which Mexican Hat wavelet is used is presented. It is an efficient chemometrics technique and has been applied successfully in processing analytical chemistry signals. It is powerful and useful information can be extracted from signals of S/N=1.
