| Abstract: | Recently, the wavelet transform is becoming a useful and effective method in the field of signal processing. Its characteristics of time-frequency localization and multiresolution are attractive for many engineering problems. The basic principle of wavelet transform and its applications to singularity detection and transient analysis are introduced briefly in the paper. Furthermore , the results of ECG signal processing are shown as an example of wavelet transform's application. |
