Abstract
Two-dimensional (2-D) discrete systems with periodic coefficients are considered for stability. These systems are called Periodically Shift Variant (PSV) digital filters and have many applications in signal processing that include the filtering of 2-D signals with cyclostationary noise, scrambling of digital images, and implementation of multirate filter banks. In this paper, the filters are formulated in the form of the well known Fornasini Marchesini (FM) state-space model with periodic coefficients. This PSV model is then studied for stability. Two sufficient conditions and one necessary condition are established for asymptotic stability.
