    It is a matter of record that the visibility of co-channel interference has maxima and minima at carrier offset frequencies which are a multiple of frame frequency. Subjective tests were made in the laboratory to determine the possible reduction in the visibility of co-channel interference by precise carrier frequency control and the stability requirements on the carrier frequency. The tests show ... View full abstract»

    A device will be described which reduces ``burn-in'' on an image orthicon tube by as much as 90 per cent. The device is relatively simple and consists of a mechanism to oscillate slowly the lens board of a television camera at a very slow rate. Electrical cancellation of the resulting horizontal motion is accomplished by simple modification to the horizontal centering circuit of the camera. This d... View full abstract»

  • The Use of A Mobile Television Monitoring Unit in an Enforcement Program

    The Mobile Television Monitoring Unit operated by the Federal Communications Commission at the present time is being used as an instrument of co-operative enforcement. Discrepancies are called to the attention of the station's technical people, working with them in a positive effort to improve the situation with the mutual goal of providing better TV service for the general public. TV station insp... View full abstract»

  • Measurement of Service Area for Television Broadcasting

    It is proposed that the present definition of television service in terms of iso-probability contours be abandoned. A new definition of service area, first proposed by Norton and Gainen in 1950, is recommended in its place. This provides a much more useful measure of service and makes the estimating techniques more tractable. View full abstract»

    A sawtooth wave contains all harmonics, and a single oscilloscope picture shows three things about an audio amplifier; flatness of frequency response, transient stability, overload. View full abstract»

  • Emergency Standby Facilities for the Aural Television Transmitter

    This paper presents a simple method for using the visual carrier of a television broadcast station for the purposes of transmitting both the aural and visual signals. The method is intended for use during emergency operation when the sound portion of the TV transmitter is ``off the air'' and the visual portion of the transmitter is in working order. This system is not recommended as a substitute f... View full abstract»
