Abstract : We consider unimodular wavelets and scaling functions whose Fourier transforms are supported in a finite disjoint union of closed intervals. In particular, we characterize those unimodular wavelets which can be associated with multiresolution analysis. As an application we have a criterion to determine whether a wavelet from a class of unimodular wavelets of Ha et al. can be associated with multiresolution analysis or not.
