The Simplification of Television Receivers

The minimum number of functions required in a TV receiver is analyzed with the purpose of reducing the required components and tubes while maintaining high quality of performance and all normally desirable features such as AGC and horizontal AFC. One of the approaches to this end has been a study of the feasibility of combining different functions in a common tube. A receiver incorporating some of the results of this study is described. Measured data taken on this receiver are presented and its general features are discussed.
