Abstract In this paper, certain problems concerning nonessential singularities of the second kind (NSSKs), especially continuous NSSKs for 3-D digital filters, are discussed. It is shown that continuous NSSKs, both inT 2 U and onT 3, may exist in stable systems. Based on the Weierstrass theorem of multidimensional complex analysis, the existence criteria of continuous NSSKs inT 2 U and onT 3 are obtained. Certain basic properties of this type of singularities are given. A stability condition for a transfer functionH(Z) with continuous NSSKs and the inverse ofH(Z) is derived. Furthermore, for isolated NSSKs, a new necessary and sufficient condition for stability is developed for a class of systems.
