Abstract :
A method for designing two-dimensional, symmetric half-plane recursive digital filters is presented: a filter is first designed as a parametrized family of one-dimensional filters; a simple approximation is then used to find a rational, stable, two-dimensional filter. Some advantages and disadvantages of the method are discussed, and several examples are given.
