Wavelet Analysis and Application

With the development of Fourier analysis,wavelet analysis become the concerned question of many subjects.On the basis of conception of wavelet transform,the Mallat algorithm has been introduced and applied on signal analysis and disposal,so a failure signal can been decomposed and restructured.Through analysis of experiment,the high frequency part can reflect the turning point,and the position of fault-point can be gained by the important information,so drew a conclusion that application of wavelet analysis is effective on the aspect of singularity measurement.
