Novel Filter Design Method using Time Domain Transforms IDS Joel Dunsmore Hewlett-Packard Company, Santa Rosa, California, U.S.A. Abstract - The author presents a novel way at approaching coupled-resonator filter design by utilizing the time domain response of the filter to establish resonator frequency and determine coupling factors. This method can also be used with coupled cavity filters, comb
