RESUMO
This work extends the classical signal subband decomposition scheme to incorporate the decomposition of linear systems. A network decomposition structure is developed to simultaneously decompose signals and systems into subband of frequencies. The procedure allows simply rate reduction, as well as the network partition repetitive subnetworks. The method uses second order allpass as decomposition/synthesis filters and a specific structure is proposed to implement the unstable synthesis filters. In the system simulation the signal is processed with very small distortion supporting the theory.
