The algorithm, which multiplies the corresponding wavelet coefficients of adjacent fine scales, enhances the feature of discontinuitypoint of signals and inhibits the effect of noise signals.
This paper gives some properties of several special function discontinuitypoint and the first kind discontinuitypoint of ordinary real function. and points out their ap-plicaion in actual problems.
