Effectiveness of Specified Error for Suppression Section in Directivity Design

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose an approximate directivity design method using MOMO(Multiplication Of Multiple Output) as a directivity design circuit. While conventional MOMO assigns multiple zeros on the unit circle, the approximate design assigns multiple zeros arbitrarily and forms directivity. Therefore, we consider that the suppression performance can be improved by adjusting the zero assignment by constraining the suppression interval of each WSC by error adjustment at the approximate interval. Therefore, we propose a method to impose specified error constraints in the suppression interval of MOMO.
