Abstract: The paper designs a parallel filter based on wavelets theory,a design algorithm of parallel wavelet filter is given and proved. The filter is composed of sampler, prefilter, analyser,frequency subsection processor and synthesizer,the principle of the filter is discussed in detail. The design can be applied in the field which need time-frequency localization.

Key words: Wavelet analysis, Principle of filter, Design
