Minimal normalized lattice structure for ARMA digital filter realization
Hon Keung Kwan, Y.C. Lui · 1991
A normalized digital lattice structure is presented for the realization of 1-D ARMA (autoregressive moving average) digital filters. The resultant realization structure is minimal in terms of the numbers of parameters and delays while possessing the desirable properties of the classical AR lattice filters. A fourth-order elliptic filter was realized using the procedures presented.>
