Abstract :
This paper develops a design of two-dimensional (2- D) stable digital filters starting from Darlington-type gyrator networks and then applying the Generalized Bilinear transformation (GBT). The coefficients of the digital transfer function are obtained as functions of gyrator constant (g), in addition to the other impedances. Design examples are given to illustrate the usefulness of the proposed technique.
