Abstract :
This work proposes a model, originated from the power spectral density concept, for the sub-band processes obtained by analysis of an ARMA process by a decimating filter bank. As an example, the model for an AR process analyzed in octaves by a tree-structured FIR filter bank is derived in a recursive way, and some interpretations are given
