  • Abstract
    This paper presents the constraints on two-dimensional γ-domain polynomials so that they possess various types of symmetries in their magnitude functions. Refering to a parameter (Δ), it is concluded that new symmetry conditions derived in γ-plane converge to those of 2-D continuous-time systems as Δ tends to zero. For analog sampled-data systems, Δ can be treated as a sampling period, otherwise it is simply treated as a design parameter
