    There has been a growing feeling, among engineers and educators alike, that there is a need at this time for a re-evaluation of the principles and goals of engineering education. This is due, in part, to the rapid progress of science and engineering in recent decades, necessitating a revision of our system of education along lines which will better serve society, the profession, and the engineer. ...

    The evolution of radar technique is traced and the radar-development program of the United States Army Signal Corps at the Signal Corps Laboratories, Fort Monmouth, New Jersey, described from its inception to America's entry in the War. Two radars developed by the Signal Corps Laboratories during this period, SCR-268 and SCR-270, are described in detail. View full abstract»

  • Frequency-Modulated Magnetic-Tape Transient Recorder

    Publication Year: 1945, Page(s):753 - 760
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5520 KB)

    A transient recorder having a frequency range of 0.02 to 1000 cycles per second with useful response up to 2000 cycles per second is discussed. The transient is recorded on a loop of magnetic tape and played back synchronously every 0.1 second on an oscilloscope screen. Thus, a steady image of the transient is obtained. Excellent signal-to-noise ratio (40 decibels) is obtained by the use of a 10-k... View full abstract»

  • The Servo Problem as a Transmission Problem

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1136 KB)

    The purpose of a servo is to reproduce a signal at a place or power level or form different from the original signal, but under its control. It is therefore a signal-transmitting system. It uses negative feedback to minimize noise and distortion, which the servo designer usually calls error. It uses mechanical and thermal circuit elements as well as electrical circuit elements, but the problems of... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3616 KB)

    A brief review of an instrument landing system is given to show where the localizer antenna fits into the over-all scheme. The localizer-antenna requirements are stated, and definitions that apply to this antenna are given. A description of an antenna that meets the specified requirements is given, including curves that show its performance over a ground plane. Patterns taken in flight on a twin-e...

  • A Proposed Standard Dummy Antenna for Testing Aircraft-Radio Transmitters

    Publication Year: 1945, Page(s):772 - 777
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1680 KB)

    A new type of dummy antenna employing a 35-foot roll of coaxial cable and a power indicator is described. It roughly simulates the impedance characteristics of an actual aircraft antenna, which is used over the range of 2 to 30 megacycles. Its impedance characteristics are not appreciably affected by mechanical shock, humidity, ageing, etc. Power measurements can be made with it over a wide impeda... View full abstract»

  • Some Considerations concerning the Internal Impedance of the Cathode Follower

    The behavior of the cathode follower working into a load consisting of R and C in parallel is investigated for step-function and sine-wave input. It is found that the tube is easily cut off for applied voltages which are decreasing functions of time. The conditions for which the tube is conductive for decreasing applied voltages are derived. They are severe for step-function input but not for sine... View full abstract»

  • Note on the Fourier Series for Several Pulse Forms

    Publication Year: 1945, Page(s):783 - 784
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (424 KB)

    Fourier-series expressions for symmetrical rectangular, triangular, and trapezoidal pulses are derived in a form from which general curves of the magnitudes of the harmonic-amplitude coefficients may be plotted. From these curves it is possible to obtain the values of the amplitude coefficients of the harmonics for any ratio of pulse duration t to cycle period T. View full abstract»

  • Analysis of Current-Stabilizer Circuits

    The performance of any current stabilizer can be predicted in terms of two parameters defined as the stabilization transconductance, gs, and the output conductance, go. Together with the equivalent circuits of Figs. 2 and 3 these two factors permit the calculation of the stabilizer performance in conjunction with any load circuit and direct-current supply. Fundamental stabili... View full abstract»

  • The Plane-Wave Resolution of Guided Waves

    Publication Year: 1945, Page(s):805 - 808
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (888 KB)

    Wave propagation in cylindrical guides of both rectangular and circular cross section is treated by representing the proper solutions to Maxwell's equation through a plane-wave expansion of the Hertzian vector. In the case of a rectangular wave guide only a finite number of plane waves (two or four) is required to represent a given mode, while for the circular guide an infinite manifold is require...

    This note shows that in many important cases the turns-ratio of iron-core transformers is given by the simple relation N1/N2= √Xsc1/Xsc2, in which Xsc1and Xsc2are the reactive components of the short-circuit primary and secondary impedance of the windings concerned. The measurements are conveniently made with an impedance or i... View full abstract»
