SECOND-ORDER TWO-DIMENSIONAL SYSTEMS: COMPUTING THE TRANSFER FUNCTION

George E. Antoniou - Marinos T. Michael

   In this paper the discrete Fourier transform is used to determine the coefficients of a transfer function of a new two-dimensional model of second-order: x(i₁+2,i₂+2)=A₀x(i₁+1,i₂+1)+A₁ x(i₁+1,i₂)+A₂x(i₁, i₂+1). The algorithm is straightforward and has been implemented using the software package Matlab^TM. Two step-by-step examples illustrating the application of the algorithm are presented.

Keywords: two-dimensional (2D) systems, second-order systems, transfer function, Fourier transform
