This paper will desctibe the basic system and its implementation in an approach to digital tuning. Many uses have been suggested for the vertical interval , including test signals, facsimile, etc. The National Bureau of Standards proposes using one of the lines for transmission of digitally encoded time information. The line chosen was originally line 1 but this was subsequently changed to line 21 due to the line 1 bypass used in broadcast processors. The information contained in the code would include -NBS time, local time, channel identification, 64 characters of text and a precise 1 MHz reference signal. The text is intended for deaf viewers, emergency codes, subtitles, network communications, etc.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1972-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114419049","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 indicating system comprises a counter, the contents of which are periodically displayed. The counter contents are preset to a value which reflects the intermediate frequency of the particular band and a submultiple of the corresponding local oscillator frequency is gated into the counter for a prescribed time interval whereby the resultant sum in the counter at the end of the prescribed time interval reflects the actual received frequency or the corresponding channel number.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1972-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129632201","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}

Operating parameters such as gain, stability, linearity, signal-handling ability, voltage output and gain-reduction capability are achieved by rather straightforward means of design. Selectivity requirements are severe, calling for placement of several specific frequencies with close tolerance within the passband of the amplifier while simultaneously attempting to reject frequencies extremely close to the edges of the desired passband. In color television receivers, the problem is especially compounded because results depend on maintenance of low phase distortion between the 6 dB points of the response curve. The new bandpass-filter IF amplifier efficiently handles these problems and helps produce a high quality picture even from a low quality signal.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1972-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123856258","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 designer then attempts to determine what section of the TV receiver is being affected by the noise. This rather unknown level and type of noise is difficult to reproduce for comparison of various receiver designs. The method here proposed to test the receiver provides a known level of noise to test for horizontal and vertical sync stability, AGC set up, and white streaking.","PeriodicalId":426905,"journal":{"name":"IEEE Transactions on Broadcast and Television Receivers","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1972-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133080928","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}
