Abstract :
It is shown that every recursible N-D IIR general-support filter has its impulse response support contained in a causality sector. A procedure to find such a causality sector in N-dimensions (N-D) is described. These results lead to simple stability theorems for general-support N-D IIR filters. It is also shown that the modeling of an N-D digital filter using causality sectors suggests a systematic method for obtaining canonical local state space representation which is compatible with its input-output description.
