| Abstract: | Wavelet packet analysis is applied broadly in signal denoising which is one of the time-frequency methods.Reference to the result of power spectrum analysis,Wavelet packet denoising is used in pretreatment of seism signal in this article,and the effect is favorable.So,it is said that Wavelet packet denoising is valuable for the high frequency and low frequency disturbances were weakened sharply using it. |
