The system features direct user-to-user communication without intermediate switching, a number of users have a common frequency band but avoid interference by operating in different time channels. Transmission takes place in bursts containing a large number of contiguous samples. This time-compression of the samples provides sufficient guard-time to accommodate the range of transmission delays in the specified area and other timing errors. A central clock is desirable but not indispensable. System calculations indicate 10 simultaneous simplex conversations per megacycle using delta modulation. The analysis assumes that subscribers are located in discrete areas. A large number of addresses, ringing and busy tones, command override, etc., are easily accommodated.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124019014","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}

It is recalled that not so many years ago, Dr. Frank B. Jewett, the renowned scientist and former President of Bell Telephone Laboratories, was once asked to define the ultimate objective of telephone communications. He replied in essence that when you can take out of your pocket a device the size of a watch, dial the number of a particular individual who may be anywhere in the world, and if he did not answer, you knew he was dead; that is the ultimate objective.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"757 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116118511","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}

However, forward-acting AGC is inherently stable, so it can be made very fast by inserting a sharp cut-off filter in the control path. This permits the suppression of 200 cps. fading with negligible effect on the 300–3,000 cps. voice band. Analysis and tests show that fading modulation products are suppressed by about 20 db.","PeriodicalId":263631,"journal":{"name":"IRE Transactions on Vehicular Communications","volume":"260 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1962-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133589619","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}
