The M-channel maximally decimated filter bank is considered, where, except in the
ideal case of perfect reconstruction, aliasing distortion, magnitude distortion,
and phase distortion are present. It is shown how these can be controlled if the
filter bank is designed by the method of [1] that optimizes the gain of an error
system.
