Using digital computer, two kinds of Gaussian noise, low pass filtered and band pass filtered, were simulated and the frequencies were counted by level crossing count, peak count, zero-crossing peak count and range-mean count methods. The first three methods showed a good agreement with Rice’s theoretical solution in the higher level, but differed each other in the lower level. When the eliminated amplitude was increased the differences between the three methods decreased, but the differences of the three methods from Rice’s solution increased. Range-mean counts were sensitive to the magnitude of the eliminated amplitude and the effect of eliminating small amplitude varied with the shape of power spectral density and the magnitude of the amplitude counted. Also, comparison was made between the range-mean counts and the amplitude frequencies calculated from the three methods of counting mentioned above.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0408000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-408","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所機体第一部"},{"subitem_text_value":"航空宇宙技術研究所機体第一部"},{"subitem_text_value":"航空宇宙技術研究所機体第一部"},{"subitem_text_value":"航空宇宙技術研究所機体第一部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"First Airframe Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"First Airframe Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"First Airframe Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"First Airframe Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山根, 晧三郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"竹内, 和之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小野, 幸一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"朝田, 洋雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YAMANE, Kosaburo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKEUCHI, Kazuyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ONO, Koichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ASADA, Hiroo","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr00408.pdf","filesize":[{"value":"536.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00408.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44656/files/naltr00408.pdf"},"version_id":"463b74cb-1c68-43f8-8849-781c10644fb0"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"数値実験による各種ひん度計数法比較","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"数値実験による各種ひん度計数法比較"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44656","relation_version_is_last":true,"title":["数値実験による各種ひん度計数法比較"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:53:11.861347+00:00"}
