STATIONARY DISCRETE WAVELET-TRANSFORMATION. APPLICATION QUESTIONS IN FILTRATION PROBLEMS

In article the basic merits and demerits of stationary discrete wavelet-transformation (SDWT) are defined. The impossibility of a complete recovery of a signal concerns the basic lacks SDWT the interpolated filters, and also increase in time uncertainty of the filter (distortions in a pass-band) with growth of level of decomposition. The algorithm of the modified stationary discrete wavelet-transformation reducing specified lacks is offered.
