The concepts and its filter of wavelet transform are introduced, the application of wavelet as a kind of new analysis tools in unstable signal analysis is presented.
In this paper, a linear function of bearing variation versus time is given, and the method of work-point drifting are used to solve filter system which is unstable in bearing small change.
