HALF CENTURY OF TELEVISION RECEPTION.

This paper, which appeared originally in 1961, is reprinted due to its historical interest. The development of television receiving is traced, starting with a description of the earliest demonstrations of mechanical television. While 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. The development of circuitry for IF, VF, and deflection is covered. A bibliography, containing some of the great historic as well as the most recent contributions, is included.
