摘要：

Using the approach described by Smith and Barnwell for obtaining exact-reconstruction filter banks, we present conjugate-quadrature and linear-phase solutions for two-channel filter banks using Lagrange halfband filters. We show that the wavelet solutions obtained by Daubechies under certain regularity conditions are the same as the conjugate-quadrature solutions derived from tagrange halfband filters using the above approach. The linear-phase solution that we describe provides filters with simple coefficients.
