    Design problems of magnetic amplifiers have been mastered by a technique which appertains to core construction, arrangement and proportioning of windings, and circuiting. Principles are described which have led to the construction of precision amplifiers adaptable to a wide range of input impedances and output requirements. Performance figures are given and practical applications described. Graphi... View full abstract»

    The problem of the minimum loss in relation to the singing point is investigated for generalized transmission systems that must be stable for any combination of passive terminating impedances. It is concluded that the loss may approach zero db only in those cases where the image impedances seen at the ends of the system are purely resistive. Moreover, in such cases, the method of overcoming the tr... View full abstract»

    A new dispenser-type emitter, known as the L cathode, is described and compared with three common types of emitters. A discussion of the methods of measuring the rate of barium evaporation is included, as well as the life performance of the L cathode in a number of diversified types of electron tubes.

    The procedure for a complete mathematical analysis of the AM-rejecting properties of the ratio detector is presented. The operation with 100-per cent efficient diodes is first treated, and it is shown that in this case compensating resistors which reduce the effective efficiency of the diodes must be used to obtain optimum AM rejection. The operation with practical diodes is then treated and desig... View full abstract»

    A traveling-wave cathode-ray tube has been developed which will record single nonrecurrent transients of 0.5 millimicrosecond rise time. The development was directed toward improvement of writing speed, deflection factor, and shielding between horizontal and vertical deflectors. Distortions due to transittime effects, and frequency dependent impedance mismatch of the deflector have been minimized.... View full abstract»

  • Some Limitations on the Accuracy of Electronic Differential Analyzers

    Electronic differential analyzers, or simulators, employ computing elements which must be physically realizable electric circuits, and this fact introduces unavoidable errors into the differential-equation solutions. These errors are investigated mathematically for the general case of differential equations with constant coefficients. It is found that in certain cases an error of 1 per cent can be...

    By combining the properties of the klystron and the distributed amplifier, the duplex traveling-wave klystron allows wide-band amplification of high-level microwave power with an efficiency approaching that of an ordinary klystron. The construction and operation of an experimental model are described briefly. View full abstract»

    The composite multiplex signals generated by frequency-division methods long standard in telephone communication, can be transmitted by the new transcontinental broad-band FM radio relays. Signal intermodulation by echoes must be minimized. Such intermodulation is investigated in this paper experimentally and analytically. Two types of echoes are considered: (1) Weak echoes with delays exceeding 0... View full abstract»

  • Techniques for Close Channel Spacing at VHF and Higher Frequencies

    Physically separated radio transmitters can be frequency-division multiplexed to obtain a great economy of bandwidth utilization at vhf and higher frequencies, by use of a common reference signal at both transmitter and receivers in lieu of locally generated high-frequency oscillations. In an individual transmitter, a modulated low-frequency subcarrier would be used to modulate a harmonic of the r... View full abstract»

    A method of connecting 90-degree audio phase-difference networks for use in selective-sideband transmission and reception is shown, whereby an over-all performance is obtained which is analogous to the cascade operation of conventional filters. Three networks are required to obtain twice the rejection in decibels of one. For best results two of the networks must be accurately matched. The cascade ... View full abstract»

    An analysis is given of some of the basic properties of exponential modes on passive cylindrical structures in which the material constants of the medium vary over the cross section. The bounding surface is assumed to be opaque, in the form of an electric or a magnetic wall; it is therefore always nondissipative. Major consideration is given to structures in which the internal medium is also nondi... View full abstract»

  • Radiation Patterns and Conductance of Slotted-Cylinder Antennas

    A narrow slot cut in the wall of a hollow cylinder is excited by a transmission line and produces radiation. A theoretical solution to the radiation patterns and conductance is obtained by solving Maxwell's equations for the fields in the far zone, and requiring them to satisfy the known boundary conditions at the surface of the cylinder. Advantage is taken of published data on potential distribut... View full abstract»
