A Half Century of Television Reception

The paper traces the development of television receiving, starting with a description of the earliest demonstrations of mechanical television. While the major emphasis is on reception, enough discussion of television system standards is included to support the development of the receiver story. The progression of events which led from the early mechanical systems, through the various phases of electronic television using cathode-ray picture tubes, up to the modern compatible color television receivers, is covered in some detail. The development of circuitry for IF, VF, and deflection is covered. A complete bibliography, containing some of the great historic as well as the most recent contributions, is included.
