摘要

利用小波分析对试验数据进行后处理，较好的消除了系统的噪音。与Fourier变换法、10点平均滤波法比较后可知，小波分析方法能较好的保留原始数据的特征信息。对目前仍因被噪音困扰而不能正常进行的试验分析提供了一条解决途径。

Abstract

The post-processing of test data is made by using wavelet analysis. The results show that the noise of system can almost be eliminated. Comparing with Fourier transform method and filter method of adopting mean value of ten points

it seems that the wavelet analysis method could better reserve the characters of original test data. A way to filter test noises that can’t be avoided

is provided.
