Abstract :
A method for designing 2-dimensional stable recursive digital filters is presented. It dispenses with the computationally difficult task of separately testing for the stability of a 2-d digital transfer function, as it is ensured at all stages in the course of an optimisation algorithm. The method is essentially based on the propeties of 2-variable positive real functions.
