✦ Synopsis

Based on the requirement of stability and causality, this paper presents a new method of designing IZR digital filters. The method is essentially a combination of a time-domain and a frequency-domain technique. The result of this method is identical to the one in ( 5) which was derived without any physical interpretation. Because of this new derivation, the method can be readily extended to two or more dimensional noncausal digital filters.
