    The three attributes of musical sound, pitch, loudness and timbre, are discussed in relation to their counterparts in an electrical signal, frequency, amplitude and harmonic spectrum. Although electrical devices can control these quantities simply according to the explicit instructions contained in written music, that is, to provide the "bare essentials" of a musical performance, it is more diffic...

    The study of nonlinearities in nature suitable for computer use has led to the cryotron, a device based on the destruction of superconductivity by a magnetic field. The cryotron, in its simplest form, consists of a straight piece of wire about one inch long with a single-layer control winding wound over it. Current in the control winding creates a magnetic field which causes the central wire to ch... View full abstract»

    Oxygen and water vapor, when individually in contact with the transistor surface, have been found to cause substantial and generally opposite changes in the characteristics of germanium alloy junction transistors. These changes, however, are reversible: by means of vacuum baking a reproducible set of characteristics can be repeatedly reestablished after water vapor or oxygen has caused a large cha...

    A new microwave detector is described which possesses extremely large bandwidth capabilities in addition to being free from power limitations. The sensitivity is comparable to that of a crystal. This new device operates on the electron beam of a traveling wave tube as a velocity sorter by utilizing the stop-band phenomenon of a periodic magnetic focusing system. The electrons are sorted according ... View full abstract»

  • Increasing the Reliability of Electronic Equipment by the Use of Redundant Circuits

    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1717 KB)

    Electronic equipments which employ large numbers of tubes and components are often unreliable because a large number of parts may fail. A means of countering the undesirable effects of increasing equipment complexity is by introducing even more tubes and components as redundant circuitry. A requirement for obtaining the conditions, in which redundancy is helpful is for the causes of failure of par... View full abstract»

  • Transformer "Miniaturization" Using Fluorochemical Liquids and Conduction Techniques

    Publication Year: 1956, Page(s):515 - 520
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2828 KB)

    Reduction of size and weight in electronic type transformers to keep pace with miniaturization in other phases of electronic component designing has led directly to higher temperature operation. Temperatures in the region of 185°C require inorganic materials throughout, including where used, the dielectric coolant. Design details and materials performance in "miniaturized" electronic type transfo... View full abstract»

    Certain broad general principles of electronic reliability become obvious when reliability is viewed as one of a number of important aspects of the broad general problem of achieving most efficient and effective performance of some desired task using electronic equipment. 1) The reliability of an electronic device or system depends not only upon the intrinsic properties of the device, but also on ...

  • A Magnetic Thyratron Grid Control Circuit

    Publication Year: 1956, Page(s):529 - 532
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1604 KB)

    A new compact magnetic method for driving thyratron grids has recently simplified high-power fast response servos and regulated power supplies. Since large power gain is available in the thyratron, power amplification can be sacrificed in the magnetic circuit to gain speed of response comparable to the thyratron inverse cycle. The new grid circuit provides a rapid rate of rise of thyratron firing ... View full abstract»

  • Analysis of a Regenerative Amplifier with Distributed Amplification

    Publication Year: 1956, Page(s):533 - 534

    It is shown that regenerative circuits of the discontinuous-output type such as the monostable multivibrator do not have their high speed performance improved by the use of distributed amplification in the amplifier portion. View full abstract»

  • Keep-Alive Instabilities in a TR Switch

    The reliability of a pulse radar system is often reduced by intermittent burnout of the receiver crystal. It has been found that one possible cause of this is the occurrence in the Transmit-Receive (TR) switch of occasional transitions from a glow to an arc of the keep-alive gas discharge. Following a transition, the keep-alive discharge is extinguished for a period of the order of fifty microseco... View full abstract»

  • The Optimum Tapered Transmission Line Matching Section

    The tapered transmission line matching section is analyzed by treating it as a high pass filter. The ideal reflection coefficient characteristic for the taper that gives the smallest pass band tolerance for a given cutoff frequency and vice versa is derived from the expression for the reflection coefficient of the optimum designed n section quarter-wave transformer by taking the limit as n tends t...

    A new waveguide rotary joint has been designed which will permit multiple stacking of similar joints on a common axis. The rotary joint of annular waveguide design will carry high power and permit low vswr and low insertion loss operation throughout the full rotation. The theory, design, and characteristics of such a joint are presented. View full abstract»

    A double-slab ferrite field displacement isolator has been constructed for the 10.7-11.7 kmc band with the following performance: reverse loss of 70 db from 10.8-11.7 kmc and 64 db at 10.7 kmc; forward loss less than 1 db, except 1-1.2 db between 11.6 and 11.7 kmc; vswr less than 1.15, except 1.15-1.20 between 11.6 and 11.7 kmc; variation in forward loss less than 0.1 db for any 20 mc channel.
