  • An Oscillator Having a Linear Operating Characteristic

    Publication Year: 1933, Page(s):14 - 28
    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1896 KB)

    A review of conventional linear equilibrium conditions is given. It is shown that these conditions are not usually at all applicable to practical oscillators because the operating region is not to be so simply described. The relation of nonlinear effects tofrequency modulation is pointed out. A modified type of oscillator which conforms to the elementary linear conditions is described and its prop...

    An analysis of a particular Lecher wire system whose characteristic impedance matches its input impedance and whose output end is short circuited, has led to an equation permitting the measurement of ultra-radio frequencies to three significant figures. The method is independent of end effects and has been applied to a determination of the velocity of propagation along iron wires. View full abstract»

    This paper gives a quantitative analysis of operating performance of a triode vacuum tube as a frequency doubler. With slight changes this analysis can be applied to tripling, quadrupling, etc. Three methods of attack have been outlined: theoretical analysis, graphical solution, and experimental results. The theoretical analysis furnishes a general solution to the problem, from which general concl... View full abstract»

  • Modulation Frequencies in Visual Transmission

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (720 KB)

    A method of computing the maximum frequencies produced in television transmission is shown. This method is based on the consideration of the degree of edge definition produced. It is shown that these frequencies are independent of the amount of detail in transmitted pictures for equal edge definition. For a picture scanned by the usual method N pictures per second, with L lines, having a ratio r o... View full abstract»

  • An Improvement in Vacuum Tube Voltmeters

    Publication Year: 1933, Page(s):56 - 62

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1440 KB)

    A vacuum tube voltmeter for the measurement of audio frequencies, which depends for its operation almost entirely upon the amplification factor of the tube, is described. This voltmeter combines the marked advantages of a single voltage source for filament, grid, and plate supply with the absence of zero adjustment requirements on the indicator. It has a further advantage over the more common type... View full abstract»

    The application of high-frequency telephone transmission to international rebroadcasting is treated. Brief descriptions are given of the method used in rating the suitability of reception for rebroadcasting, the effects of magnetic disturbances upon transmission, the correlation of magnetic activity with transmission, and the forecasting of magnetic disturbances and resultant transmission conditio...

  • North Atlantic Ship-Shore Radiotelephone Transmission during 1930 and 1931

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3096 KB)

    Considerable data on radio transmission were collected during the years 1930 and 1931 incidental to the operation of a ship-shore radiotelephone service with several passenger ships operating in the North Atlantic. This paper discusses briefly the results of an analysis of these data. Contour diagrams are given which show the variation of signal fields with distance and time of day for the various...

  • Short-Wave Transmission to South America

    The results of a year's survey of transmission conditions between New York and Buenos Aires in the short-wave radio spectrum are presented in this article. Surfaces showing the received field strength as a function of time of day and frequency are given. These show that frequencies between 19 and 23 megacycles were best for daytime transmission, and those between 8 and 10 megacycles for nighttime ... View full abstract»

    The aim of this article is to deduce the design data on frequency transmission, which are necessary in designing the networks for high-frequency modulated waves. In the first section the general laws of current variations in circuits tuned to carrier frequency with and without tube generator are derived; the interdependence of current curves of various circuits forming a given network is also clar...

    The problem considered in this paper is that of setting up an exactly equivalent circuit for a four-terminal network containing one e.m.f. and any number of impedances connected in any manner. Several relatively simple circuits which can be used to represent any such active network, and some others which can be used in special cases, are completely specified. View full abstract»

  • Mutual Impedance of Two Skew Antenna Wires

    In a recent communication P. S. Carter derived a formula for the mutual impedance of two antenna wires intersecting at an angle θ, as a sum of two definite integrals. It has been shown that related double integrals can be reduced to sums of logarithmic integrals and their limits; in the present paper this reduction will be generalized. The mutual impedance of two antenna wires in space which ... View full abstract»
