Treatment of Watelet Transform for Square Wave Noise in MT Date

FAN Cui-song,LI Tong-lin,WANG Da-yongCollege of GeoExploration Science and Technology,Jilin University,Changchun 130026,China  
This article analyses the original data of MT which contains noises of square wave,and found out the noise Source,and reorganizes the low frequency interference,using wavelet transform,then erases the interference.According to conventional methods,we can get the power spectrum.The result shows that this method gets good effects.
