| Abstract: | Sharp changes or change tendency characters of a signal, which are singularities of the signal, are studied in this paper. Moreover, a special integral wavelet transform is used for determining the locations of the singularities of the signal. Two numerical experiments are presented to illustrate the effectiveness of the method. |
