Removing Noises from Signals of Motor Measurement by Wavelet Packet

Wei Yunbing Huang Jin Huang Jianhua(Zhejiang University 310027 China)  
As a new technique of signal processing,wavelet analysis has excellent characteristics of time frequency localization and is suitable for analyzing time varying or transient signals.This paper proposes the floating threshold algorithm based on wavelet packet transform to remove the noises from the signals of motor measurement.The experimental results show the favorable characteristics of the algorithm.
