Abstract :
A time-domain approach to the design of compactly supported wavelets is considered. The time-domain formulation has resulted in a unified design approach for uniform, nonuniform, low-delay, and efficient analysis-synthesis filter banks. Because of the generality of the framework, regularity and phase conditions can easily be imposed on the wavelet. Because the design procedure can be used for nonuniform band systems, decompositions with higher frequency resolution than that of dyadic wavelet-based systems can be designed and realized. Design examples are included
