The critical problem is the representation of a signal using a small number of computable functions, such that it is represented in a concise and computationally efficient form. It is shown that wavelets are closely related to filter banks (sub band filtering) and that there is a direct analogy between multiresolution analysis in continuous time and a filter bank in discrete time. This provides a clear physical interpretation of the approximation and detail spaces of multiresolution analysis in terms of the frequency bands of a signal. Only orthogonal wavelets, which are derived from orthogonal filter banks, are discussed. Several examples and applications are considered. date: 2000 type: Study Group Report type: NonPeerReviewed format: application/pdf language: en identifier: http://miis.maths.ox.ac.uk/miis/377/1/Orthogonal-wavelets-via-filter-banks.pdf identifier: Winkler, J.R.
