✦ Synopsis

In this paper we present an alternative approach to the direct design of 1-D recursive digitalfilters satisfying prescribed magnitude specifications with or without constant group delay characteristic. This method uses an iterative method to calculate the coejkients of the$lter's transfer,function and guarantees the stability of the designedjlter using a new stability test reported by Ramachandran and Gargour. To illustrate the usefulness of the technique, examples are given.
