Abstract

We consider a multi-input, multi-output lattice realization for linear time-varying analysis banks which are all pass. Such a realization was given by Vaidyanathan and Mitra (1985) for linear time invariance (LTI) systems; and under certain conditions generalizes to the linear time varying (LTV) case. Moreover, our implementation is simpler than the one presented by Vaidyanathan et al. Finally, we describe the anticausal inverse of a lattice realization which is used in the synthesis bank.
