  • Some Comparative Factors of Picture Resolution in Television and Film Industries

    Publication Year: 1951, Page(s):6 - 10
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1128 KB)

    This paper reviews and compares the quantitative meaning of the term "resolution" as commonly used by the television industry and the film industry. The danger of using values of limiting resolution as the sole measure of picture quality is discussed. Conversion equations are developed and a table listing numerically equivalent values of resolution is provided. View full abstract»

  • Correction of Deflection Defocusing in Cathode-Ray Tubes

    Publication Year: 1951, Page(s):10 - 15
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (912 KB)

    This investigation deals with the problem of minimizing spot distortion by suitable design of the deflecting plates in a cathode-ray tube with electrostatic deflection. The treatment is mathematical throughout. A number of the results obtained may be applicable to a much wider range of problems. A number of special design formulas are given which solve the problem satisfactorily. View full abstract»

  • Progress in Development of Test Oscillators for Crystal Units

    Publication Year: 1951, Page(s):16 - 26

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2688 KB)

    Early crystal unit test oscillators as conceived some 20 years ago were principally duplicates of the actual equipment in which the crystal units were to be utilized, a practice which resulted in a large variety of test circuits and procedures for testing. It is now recognized that a knowledge of the equivalent electrical elements making up the crystal unit is essential to the circuit engineer, an... View full abstract»

  • A Multichannel PAM-FM Radio Telemetering System

    Publication Year: 1951, Page(s):36 - 43

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2400 KB)

    A multichannel time-division system of the PAM-FM type is described. It can provide as many as 64 channels with an information bandwidth per channel greater than 800 cps or fewer channels with a corresponding increase in the information bandwidth per channel. Modulation and multiplexing in the airborne equipment, and demultiplexing in the ground station, are performed by simple pentode gating circ... View full abstract»

  • Quantization distortion in pulse-count modulation with nonuniform spacing of levels

    Publication Year: 1951, Page(s):44 - 48
    Cited by:  Papers (88)  |  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (789 KB)

    It is shown that the distortion introduced in a pulse-count-modulation system due to quantization can be minimized by nonuniform spacing of levels. Equations are derived for an arrangement of nonuniform level spacing that produces minimum distortion. It is also shown that minimum distortion is significantly less than distortion resulting from uniform quantization when the crest factor of the signa... View full abstract»

  • Radiation from Wide-Angle Conical Antennas Fed by a Coaxial Line

    An approximate expression for the radiation from spherically capped conical antennas is derived by the Fourier-Laméeigen-function method. Radiation patterns have been calculated for antennas with flare angle of π/6 and various lengths. View full abstract»

  • Angular Jitter in Conventional Conical-Scanning, Automatic-Tracking Radar Systems

    Publication Year: 1951, Page(s):51 - 55
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1720 KB)

    Four sources of angular jitter in a conventional conical-scanning, automatic-tracking radar are discussed and each is expressed in terms of range and the several system parameters. The total-angular-jitter-versus-range curve is shown to have a characteristic shape exhibiting a certain range interval of optimum tracking. The importance of beamwidth in determining the magnitude of angular jitter is ... View full abstract»

  • The Statistical Properties of Noise Applied to Radar Range Performance

    Publication Year: 1951, Page(s):56 - 60

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1312 KB)

    The advent of high-speed scanning radars which yield but a few pulses per scan element and displays which collapse the range co-ordinate has necessitated an analytical approach to the problem of radar range performance, as empirical methods have proven inadequate. An analysis is made which yields several graphs from which the radar detection range can be calculated for any desired detection probab... View full abstract»

  • Principles of the Electrical Rating of High-Vacuum Power Tubes

    Publication Year: 1951, Page(s):60 - 69
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1704 KB)

    A rational system of ratings for high-vacuum power tubes has been arrived at, which permits the determination of ratings by calculation, once the radio-frequency power amplifier and oscillator ratings, class C, have been determined by operating test and life test. A summarized tabulation of the rating factors is given. A system for reducing ratings at high frequencies is also developed. View full abstract»
