Abstract

Based on the Fornasini-Marchesini (FM) second local state-space (LSS) model, an efficient algorithm is developed to derive the characteristic polynomial and the inverse of the system matrix from the state-space parameters. As a results, the external description of the FM second LSS model is clarified. The FM second LSS model is then used to design 2-D state-space digital filters in the frequency domain. The resulting filter approximates both magnitude and group delay specifications, and its stability is always guaranteed
