Abstract :
In this brief we consider the open problem concerning the BIBO stability of N-D digital filters with nonessential singularities of the second kind in the region U¯N-UN. We apply transformations to reduce the transfer function to the two-dimensional (2-D) case. Illustrative examples are included
