However, the filters designed with this method are not always the maximal ripple filters. This paper presents an evaluation of FIR filters using the wave moments and how to find easily the maximal ripple filters. Herrman and Schuesssler proposed a method (HS method) to transform equiripple linear phase filters into an equiripple minimum phase filters with half the degree and the magnitude characteristic equal to the square root of the prototype. However, this method is limited by a numerical complexity. The HS method has been improved and used. But the filters are not always an equiripple in a passband. In this paper, we define the equiripple scale (Er) in a measure of the ripple. And we show the relation between Er and linear phase FIR filters as prototypes in the design of minimum phase filters.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"1804","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ヨシカワ, トシノリ"}]},{"nameIdentifiers":[{"nameIdentifier":"1805","nameIdentifierScheme":"WEKO"}],"names":[{"name":"テシマ, マサノブ"}]},{"nameIdentifiers":[{"nameIdentifier":"1806","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshikawa, Toshinori"}]},{"nameIdentifiers":[{"nameIdentifier":"1807","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Teshima, Masanobu"}]}]},"item_4_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長岡技術科学大学"}]},"item_4_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00177120","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0388-5631","subitem_source_identifier_type":"ISSN"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"長岡技術科学大学電気系"},{"subitem_text_value":"長岡技術科学大学電気系"}]},"item_4_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉川, 敏則"}],"nameIdentifiers":[{"nameIdentifier":"1802","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"手島, 雅延"}],"nameIdentifiers":[{"nameIdentifier":"1803","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-08-03"}],"displaytype":"detail","filename":"K11_5.pdf","filesize":[{"value":"417.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"K11_5.pdf","url":"https://nagaokaut.repo.nii.ac.jp/record/508/files/K11_5.pdf"},"version_id":"970a54ea-49fb-4d48-b855-05aaca23d381"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"FIR digital filter","subitem_subject_scheme":"Other"},{"subitem_subject":"maximal ripple filter","subitem_subject_scheme":"Other"},{"subitem_subject":"equiripple","subitem_subject_scheme":"Other"},{"subitem_subject":"minimum phase","subitem_subject_scheme":"Other"},{"subitem_subject":"wave movement","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"FIRディジタルフィルタのリプル評価について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"FIRディジタルフィルタのリプル評価について"}]},"item_type_id":"4","owner":"2","path":["50"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-02-14"},"publish_date":"2011-02-14","publish_status":"0","recid":"508","relation_version_is_last":true,"title":["FIRディジタルフィルタのリプル評価について"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T18:59:21.956433+00:00"}
