Abstract

This paper deals with the definitions and the testing for the presence of various symmetries in the magnitude response of two-dimensional (2-D) delta operator formulated discrete-time systems. The symmetry constraints defined provide a unification with the analog 2-D case. With the sampling period=0, the results correspond to the conditions on analog polynomial magnitude symmetry
