Abstract: 
In this paper we study the structure of prefilters which ensure a certain approximation order of a given multifilter system. We show how all prefilters can be obtained from the generic one and that in general these prefilters are necessarily rational filters, but point out how a judicious choice of parameters can be used to obtain FIR filters for the approximation orders 1, 2, 3. Moreover, we illustrate the results by giving prefilters for the standard examples of multiwavelets. (C) 2007 Elsevier B.V. All rights reserved.
