Detailed Description

A base class for wavelet family filters.

Author: John Clyne

Version: $Revision$

Date: $Date$

The WaveFiltBase class is a base class for building classes of wavelet families that can be implemented as FIR filters. A wavelet family class contains scaling and wavelet coefficients that define a particular wavelet. All filters are normalized.
