Optimal design of multi-channel, uniform-band transmultiplexers is consider
ed. A criterion based on 2-norm of transfer matrices is proposed to quantif
y the degree of closeness to perfect reconstruction; connections of this er
ror criterion to the traditional cross-talk, magnitude, and phase distortio
ns are established An optimal design procedure for FIR analysis filters is
developed and applied to two design examples. (C) 2000 Elsevier Science B.V
