The purpose of this paper is tot discuss another significant aspect of any communication system, which is the system signal to noise improvement. The basic mechanisms of fluctuation noise generator of PTM signal is the synchronizing action of pulse oscillator by valve noise. If the pulse time is shorter compare with the build up time of oscillation, the shape of pulse is distorted and the efficiency decreases. In order to improve the S/N, distortion and oscillation efficiency, kernel oscillator is profitable and, moreover, impulsive kernel oscillator has produced many valuable results. These oscillator synchronizes the main pulse oscillation overcoming the fluctuation noise within the range of 60 db. of S/N up to the frequency of micro wave signal.","subitem_description_type":"Abstract"}]},"item_10_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_10_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"信州大学工学部紀要 4: 55-66 (1954)","subitem_description_type":"Other"}]},"item_10_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"信州大学工学部"}]},"item_10_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0037-3818","subitem_source_identifier_type":"ISSN"}]},"item_10_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00121228","subitem_source_identifier_type":"NCID"}]},"item_1627890569677":{"attribute_name":"出版タイプ","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":"石田,  光夫","creatorNameLang":"ja"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-28"}],"displaytype":"detail","filename":"Engineering04-04.pdf","filesize":[{"value":"557.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Engineering04-04.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/13207/files/Engineering04-04.pdf"},"version_id":"c32cb6cc-fc98-4c5d-bcfa-634ef43eea33"}]},"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":"PTM 通信方式の雑音と核発振器","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"PTM 通信方式の雑音と核発振器","subitem_title_language":"ja"},{"subitem_title":"SIGNAL TO NOISE IMPROVEMENT IN A PTM SYSTEM (KERNEL OSCILLATOR)","subitem_title_language":"en"}]},"item_type_id":"10","owner":"1","path":["1303"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-01-05"},"publish_date":"2011-01-05","publish_status":"0","recid":"13207","relation_version_is_last":true,"title":["PTM 通信方式の雑音と核発振器"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-03-16T05:42:51.081072+00:00"}
