    This paper describes the objectives, mechanical and electrical problems and solutions, and final performance of the multiple antenna system for television and FM broadcasting on the Empire State building in New York City. A specially built steel tower supports six individual antennas from which there are transmitted five picture carriers, five sound carriers, and three FM broadcasting carriers wit...

    The generation of compatible color signals according to NTSC specifications is covered in this paper. The equation for the composite signal is stated in terms of voltages existing in the red, green, and blue channels, and methods of calculating and measuring the composite video signal produced by a synthetic color bar chart generator are given. The development of the signal from the channel output... View full abstract»

    The circular electric mode in round metallic tubing becomes increasingly more attractive than the dominant mode from the standpoint of minimzing the waveguide size at frequencies above about 10,000 mc for the loss criterion of 0.25 db/100 feet. The circular electric (TE01) mode also makes available a theoretical heat loss of 2 db/mile in waveguides less than 6 inches in diameter at frequencies hig... View full abstract»

    The unconventional behavior of permeability and core loss in the magnetic ferrites as compared to metals has led to a study of core-loss measurements. The relationships between the magnetic quality factor ¿Q and the characteristics of coils and transformers are developed, and the advantages of ¿Q as a parameter for the study and application of ferrites are discussed. A selected bibliography is g... View full abstract»

  • The Effect of Impurity Migrations on Thermionic Emission from Oxide Cathodes

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (892 KB)

    A comparison of thermionic emission from oxide cathodes with different base alloys showed the dependence of the work function on migrating impurities from tube parts other than the cathode. The effect of the base metal alone could be evaluated properly only by the use of a special diode structure which did not contribute any impurities toward the reduction of the oxide-coating. In the test method ... View full abstract»

  • Electrically Tuned RC Oscillator or Amplifier

    Two RC circuits based upon all-pass phase-shift networks are described. They are useful as electronically tunable audio oscillators, selective amplifiers, or bridges. Change of resonant frequency is accomplished by varying amplitude of transmission in one or more circuit branches by means of vacuum-tube modulators. In theory, both circuits may be electronically tuned from zero to infinite frequenc... View full abstract»

  • The Principle of a Servo-Type Mechanism Requiring Variable Elements

    Publication Year: 1953, Page(s):373 - 377
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1062 KB)

    The subject of this article is the theoretical synthesis of a mechanism which has some essential features in common with conventional servomechanisms and some with analog computers. It operates on a feedback principle; that is, at one point of the system an input is compared with a signal fed back from the outputs of the device, and an error signal is derived from this comparison. The basic distin... View full abstract»

  • Filter Transfer Function Synthesis

    In this paper we shall discuss a method for the synthesis of transfer functions which have one or more steady-state frequency bands throughout which a constant-amplitude level is approximated. Filters and amplifiers are familiar examples of circuits which commonly use transfer functions of this kind. The salient points of this method as applied to some low-pass filter examples will be considered h... View full abstract»

  • Stabilization of Nonlinear Feedback Control Systems

    Conventional methods for linear systems may be used for determining the operating characteristics of a nonlinear device near equilibrium, provided the differential equations expressing its operation can be expanded in a Taylor series about the equilibrium point. These methods are justified only for variations about equilibrium sufficiently smnall that all second and higher power terms of the expan... View full abstract»

  • Nomograms for the Computation of Tropospheric Refractive Index

    Publication Year: 1953, Page(s):385 - 391
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (790 KB)

    Three sets of nomograms permitting calculation of tropospheric refractive index, refractive index discontinuity, and vertical refractive index gradient are presented. So far as is known, no similar charts have been made for discontinuity and gradient calculations. All three have been designed about the standard radiosonde transmission, which gives temperature, dew-point temperature, and pressure a... View full abstract»

  • The Maximum Gain of an RC Network

    It is shown that voltage gains of any preassigned magnitude may be achieved at a real frequency by means of physical RC two terminal-pair networks, either grounded or ungrounded. However, the maximum gain possible by means of any RC network having a transfer function of fixed degree is bounded and the relationship between the maximum gain and the degree is determined. The results are illustrated b... View full abstract»
