          <dc:description>指向性形成回路として MOMO (Multiplication Of Multiple Output) を用いた指向性の近似設計手法を提案している．従来の MOMO は零点を単位円上に配置するのに対し，近似設計では任意に零点を配置し，指向性を形成する．そのため，各 WSC の抑圧区間に制約を与えて零点配置を調整すれば，近似区間の誤差調整により抑圧性能が向上すると考えられる．そこで，本研究では MOMO の抑圧区間に指定誤差を与える手法を提案する．</dc:description>
          <dc:description>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.</dc:description>
