The delta function showing the existence of the echo is scarcely overlooked because of its sharpness and easily detectable even if the band width of the time series is not wide enough and if the delay time of the echo is small. Experiments of sound propagation and flexural wave propagation show the effectiveness of this method. Comparison between this method and correlation method is also shown.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA2401182000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Aeronautical Science,University of Tokyo"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0372-1418","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00675986","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"KOBATAKE, Hidefumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA2401182.pdf","filesize":[{"value":"537.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA2401182.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34500/files/SA2401182.pdf"},"version_id":"62284f07-6dc1-4a22-a046-59a76a1682fd"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Detection of Echo by Linear Prediction","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Detection of Echo by Linear Prediction","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1992"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34500","relation_version_is_last":true,"title":["Detection of Echo by Linear Prediction"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:40:46.385696+00:00"}
