Oscilloscope patterns are generated on the panel by a point-by-point plot of suitably processed X-and Y-input signals.","PeriodicalId":136909,"journal":{"name":"Ire Transactions on Broadcast and Television Receivers","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1961-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116629298","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}

The basic electrical similarity between tuners of different manufacturers is pointed out, which suggests that significant design improvement might best be obtained by concentrating attention on mechanical rather than electrical factors. Development of a new compact tuner was begun with maximum use of molded plastic parts, reduction of the number of mechanical parts, and suitability for automatic production techniques as the main design objectives. A final design was completed and the tuner is now in production. A description of the novel features of this tuner indicates how the design objectives were reached and greater product uniformity and lower costs realized.","PeriodicalId":136909,"journal":{"name":"Ire Transactions on Broadcast and Television Receivers","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1961-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116762034","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}

A vector analysis of a tuner exhibiting an equivalent 5 usec. deemphasis in its output voltage vs. frequency characteristics shows that the major cause of poor stereo performance is related to the level differences of the L + R and L - R channels. A simple adjustment of the L + R level control in the synchronous oscillator stereophonic adapter circuit described can correct this difference.","PeriodicalId":136909,"journal":{"name":"Ire Transactions on Broadcast and Television Receivers","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1961-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121462490","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}

This study examines problems of broadcasting via satellites directly to home television receivers, compared with those of relaying to earth-terminals and rebroadcasting locally. The former eventually may be possible, but would require high-power, highly engineered satellites and would involve other problems, which are discussed here. Direct FM audio broadcasting may be less difficult but also less spectacular and rewarding.","PeriodicalId":136909,"journal":{"name":"Ire Transactions on Broadcast and Television Receivers","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1961-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129011398","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}
