These, combined with a novel automatic level control circuit (ALC) that does not reduce transistor current, has made these results possible.","PeriodicalId":291824,"journal":{"name":"39th Annual Symposium on Frequency Control","volume":"402 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1985-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133200200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
