| Abstract: | This paper briefly expounded the basic theory of wavelets and wavelet packet,and on the basis of using wavelet packet,introduced the general principles in vibration signal denoise.Finally,through computer simulation,for a vibration signal containing random noise,the paper made a comparison on results of vibration signal denoise between using wavelets and using wavelet packet in acquiescent threshold. |
