Parseval’s theorem proof

Web12 Apr 2024 · An A-dilation s-elementary Parseval frame multiwavelet with length m that is defined on a frame multiwavelet set of multiplicity m is said to be intrinsic. It is known that a single A-dilation s-elementary wavelets exist in L^2(\R^d) for any expansive matrix A. WebProofs of Parseval’s Theorem & the Convolution Theorem.
