Abstract :
Consideration is given to the open problem concerning the BIBO (bounded-input, bonded-output) stability of inverse 2-D digital filters in the presence of nonessential singularities of the second kind on T2, the distinguished boundary of the unit bidisk. Necessary and sufficient conditions are obtained for the BIBO stability as well as the boundedness of a large class of mutually inverse 2-D digital filters having such singularities on T2. Some illustrative examples are included
