Recently, PC audio systems as sound reproduction equipment are popular. The sound quality deterioration would be affected by D/A conversion are performed inside PC. The other hand, it is said that the sound quality are deteriorated with the hardware requirements of PC. These causes might be digital signal jitter in clock signal of D/A conversion. Jitter is fluctuation of the time interval upon digital pulse waveform. If jitter is contained in digital signal, the analog output signal which should not change theoretically will change, and sound quality will be deteriorated. To clarify cause of these deteriorations of sound quality, we devised D/A Converter and PC audio system and measurement experiment was proposed. The significant difference in value of jitter in D/A conversion clock was measured when CPU and memory equipment of PC were changed.\n","subitem_description_type":"Abstract"},{"subitem_description":"本報告では, オーディオ用PC の動作環境とサンプリングClock のjitter との関係性に着目し，高品位音楽再生を目的としたPC オーディオシステムの構築を目指す．","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"学校法人ものつくり大学"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2185-3746","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"三井, 実"},{"creatorName":"ミツイ, ミノル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"307","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金子, 大介"},{"creatorName":"カネコ, ダイスケ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"308","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"赤堀, 肇"},{"creatorName":"アカホリ, ハジメ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"309","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石川, 智治"},{"creatorName":"イシカワ, トモハル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"310","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮原, 誠"},{"creatorName":"ミヤハラ, マコト","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"311","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MISTUI, Minoru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"312","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KANEKO, Daisuke","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"313","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"AKAHORI, Hajime","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"314","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ISHIKAWA, Tomoharu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"315","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MIYAHARA, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"316","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":"2017-06-07"}],"displaytype":"detail","filename":"bulletin_77.pdf","filesize":[{"value":"544.7 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"PCオーディオシステムにおける動作環境とディジタル信号上のjitterとの関係","url":"https://iot.repo.nii.ac.jp/record/100/files/bulletin_77.pdf"},"version_id":"2057e46d-d648-460a-a657-94c5d1fee8a7"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Digital signal jitter","subitem_subject_scheme":"Other"},{"subitem_subject":"PC audio systems","subitem_subject_scheme":"Other"},{"subitem_subject":"Hardware requirements of PC","subitem_subject_scheme":"Other"},{"subitem_subject":"Digital signal jitter","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"PC audio systems","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hardware requirements of PC","subitem_subject_language":"en","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":"PCオーディオシステムにおける動作環境とディジタル信号上のjitterとの関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PCオーディオシステムにおける動作環境とディジタル信号上のjitterとの関係"},{"subitem_title":"The Relationship between Hardware Requirements of PC and Digital Signal Jitter on PC Audio Systems","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["10"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-06-07"},"publish_date":"2017-06-07","publish_status":"0","recid":"100","relation_version_is_last":true,"title":["PCオーディオシステムにおける動作環境とディジタル信号上のjitterとの関係"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-15T11:09:15.927366+00:00"}
