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.

Key words: wavelet analysis, test data, filter noise of signal
