✦ Synopsis
In this paper, a method for the design of 2-D analog and recursive digitaljlters is presented. Starting from a structure in the analog domain, suitable even or odd parts of twovariable Hurwitz polynomials are generated. This enables 2-variable very strictly Hurwitz polynomials (VSHP) to be obtained,? thus avoiding non-essential singularities of the second kind. Thus it will ensure a stable 2-D recursive digital filter obtained by the use of bilinear transformations. Examples are given to illustrate the method.
