Abstract
The authors present a perfect reconstruction FIR (finite-impulse response) linear-phase lattice structure for the two-channel quadrature-mirror-filter (QMF) bank. This structure covers most pairs of perfect reconstruction FIR linear-phase analysis filters which have the same (odd) order. For general number of channels M, conditions are derived which any QMF perfect reconstruction linear phase structure must obey. A design example is presented for the M=2 case.<>
