Abstract :
In this paper, a minimal normalized ARMA lattice filter structure for the realization of an arbitrary digital filter is presented. The filter structure is minimal in terms of the numbers of coefficients and delays, and exhibits a high degree of structural regularity and modularity. A Levinson-type algorithm is used to design the reflection coefficients. The magnitude of the reflection coefficients of such a stable filter is bounded by unity and consequently stability can be checked easily. Two IIR digital filter design examples are given.
