General results concerning the BIBO stability of inverse 2-D digital filters
The problem concerning the bounded-input-bounded-output (BIBO) stability of two-dimensional digital filters in the presence of nonessential singularities of the second kind on T/sup 2/ is discussed. Necessary and sufficient conditions are obtained for the BIBO stability, as well as the boundedness of a large class of mutually inverse two-dimensional digital filters having such singularities on T/sup 2/. Some illustrative examples are included.<<ETX>>
