摘要：

The wavelet packet transform. (WPT) is studied as a tool of multiresolution analysis for electroanalytical chemistry responses. Together with the study of the feature of WPT for white noise, an adaptive wavelet filter which can select the optimum critical level of related frequency band automatically was developed for various signals with lower frequency band, such as voltammograms, chromatograms, FIA responses. This adaptive wavelet filter can also be applied in the case of power supply interference existing.
