# Two-dimensional Hurwitz Polynomials

Conference paper

## Abstract

The progress in two-dimensional (2-D) signal and image processing activities has stimulated active research in 2-D circuits and systems. Two-dimensional digital filters are finding applications in many areas of signal processing. Two-variable (2-V) or 2-D Hurwitz polynomial study finds application in areas such as: generation and testing of (2-V) reactance functions; bounded/positive real functions, and matrices; testing the stability of 2-D digital filters, and the generation of stable 2-D transfer functions. Stability analysis is an important aspect of the design of dynamical systems.
