Abstract

In this article we introduce a new approach for orthogonal wavelet synthesis. The new approach is more general than Daubechies approach and can be used to synthesize more computationally efficient wavelets fro VLSI implementations. In order to synthesize new wavelet family we impose alternative conditions on wavelet filters. The new wavelet family is more computationally efficient than equivalent Daubechies wavelets and gives better results in terms of signal compression.
