    Results are given of subjective tests designed to determine the importance of random interference in various portions of the video band for monochrome and color pictures. Weighting functions are derived enabling random interference to be measured so that equal measured magnitudes correspond rather uniquely to equal interfering effects, regardless of the frequency composition of the random-type int...

  • Plug-in units for long lines circuits

    Publication Year: 1962, Page(s):326 - 329

    The extension of dialing, ringing, and supervision ranges in a voice-frequency telephone circuit is achieved by a unit which requires no local ringing generator and has self-contained power supply. Two extension circuits and the necessary power supply, which has an alarm in case of failure, are mounted on a portable plug-in unit. View full abstract»

  • Selective control for conventional teletypewriter and high-speed data systems

    Publication Year: 1962, Page(s):329 - 333

    Selective operation of party-line digital communications circuits is discussed, and a requirement for selective control to be divorced from teleprinters is developed. A solid-state (transistorized) selector, which is capable of operating with any class of equipment and is not dependent on teleprinters for its operation, is described in detail. This selector is capable of operating at speeds up to ... View full abstract»

  • A communications engineer looks at conical scanning

    Publication Year: 1962, Page(s):334 - 339

    The conical-scanning (con-scan) technique for automatic antenna control generates a double-side-band suppressed carrier (DSSC) signal, which must retain its absolute side-band-carrier phase and amplitude relationship for proper antenna operation. Definite passbands must be allowed in order to permit frequencies in the neighborhood of the nutation, or periodic movement, rate to pass through the sys... View full abstract»

  • A differential thermocouple voltmeter

    Publication Year: 1962, Page(s):339 - 344
    Cited by:  Papers (1)

    An a-c voltmeter has been developed to indicate directly the percentage difference between an unknown voltage and the settings of the instrument dials. It is accurate to 0.05% from 5 cps (cycles per second) to 10 kc within the voltage range from 1 to 700 volts. Two 10-ma (milliampere) thermoelements are used; one in series with an a-c decade resistor, and the other energized from a constant-voltag... View full abstract»

  • A study of dual sensing in reactor controls

    Publication Year: 1962, Page(s):344 - 347
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1351 KB)

    A problem of dual sensing is postulated wherein a reactor power level is monitored with two unlike sensing devices ¿ a slow sensor, and a fast sensor that is subject to error due to drift. An error channel, designed to combine the outputs of the two sensors so as to eliminate the undesirable characteristics of each and yield a combined output more satisfactory than that realizable from either sen...

  • Long-ranse outlook for oceanographic telemetering

    Publication Year: 1962, Page(s):348 - 350

    This paper considers the problems of the oceanographer in obtaining space in the electromagnetic spectrum for long-range radio telemetry. Among possible methods proposed is that of radio interrogation of buoys and the ¿squirt¿ transmission of data in the high-frequency range. Problems of interference with existing missile ranges are discussed. It is suggested that very high frequency and ultrahi... View full abstract»

  • A high-gain push-pull magnetic amplifier with limited circulating currents

    Publication Year: 1962, Page(s):350 - 358
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1548 KB)

    This paper describes a high-gain phase-sensitive magnetic amplifier,1,2 which simultaneously possesses the high-gain property of the self-saturating (100% positive feedback) amplifiers and the limited circulating current property of the low-gain zero feedback amplifiers. These features are obtained by using feedback windings to obtain the self-saturating large-gain property. However, these winding... View full abstract»

  • The development of the current comparator, a high-accuracy A-C ratio measuring device

    Publication Year: 1962, Page(s):359 - 368
    Cited by:  Papers (28)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5196 KB)

    The current comparator is a stable, sensitive, and reliable magnetic device, which may be used for a-c ratio measurements of high accuracy. The sources of error in such a device are discussed, and methods are proposed for minimizing their effect. The design of a 2,000-amp (ampere) feed-through current comparator based on these investigations is described, and test results are given which indicate ... View full abstract»

    The definition of ground resistance and ground impedance in the case of alternating currents is discussed. Ground resistance measurements with earth testers are compared with power frequency methods and the errors associated with the location of auxiliary grounds are described. It is emphasized that the ultimate purpose of testing station grounds is to determine touch voltages and potentials arisi... View full abstract»

  • Electrospheric and magnetospheric phenomena

    A LARGE BODY of literature deals with charged particles and the influence of electric fields on such particles. This paper presents new observations in which conducting spherical bodies themselves cause electrification by moving over the surface of a dielectric; and which, if of proper size range, display interesting static and dynamic effects. Also described are a number of new phenomena in which... View full abstract»

  • Minimal sums for boolean functions having many unspecified fundamental products

    Many techniques have been developed for finding minimal sums and minimal products for Boolean functions. In all of these techniques, it is necessary to use either all of the fundamental products which must be included in the function and all of the unspecified fundamental products (¿don't cares¿) or all of the fundamental products which must not be included in the function and all of the unspeci...
