Design of Stable 3D Recursive Digital Filters Using 3-Variable Very Strictly Hurwitz Polynomial
I. El-Feghi · Journal of Circuits Systems and Computers · 2000
In this paper, methods for generating 3-variable Very Strictly Hurwitz Polynomials (VSHP's) are presented. It is shown that the derived 3-variable VSHP's could be used to design stable three-dimensional digital filters satisfying prescribed magnitude specifications.
