Dyadic Filter Bank Design

Design of dyadic filter banks using the window method for FIR digital filter design (introduced in §E.4) is described in, e.g., [214, §6.2.3b].

A ``very easy'' method suggested in [266, §11.6] is to design a two-channel paraunitary QMF bank, and repeat recursively to split the lower-half of the spectrum down to some desired depth.
