  • A transfluxor program store for an airborne digital computer

    Publication Year: 1966, Page(s):270 - 276

    Non-destructive read-out devices for digital computer storage can have two advantages over volatile storage. Program information may not be lost in the event of computer or power supply malfunction, and economy can often be achieved in drive circuitry and power consumption. The transfluxor can be used for a store which has both these advantages, and is, moreover, electrically alterable at microsec... View full abstract»

    Recent measurement procedures used between 1 Mc/s and 40 Gc/s in evaluating very high cut-off frequency varactor diodes are discussed. The types of measurement are: bridge measurements at low frequencies, microwave coaxial line measurements, a transmission method near the diode series-resonant frequency, and a transmission method at diode parallel resonance. Typical results from each type of measu... View full abstract»

    A specialized data processing machine is being developed, which will be capable of using data from an array of seismometers to derive information on the direction of arrival, phase velocity and energy-time distribution of body waves from distant seismic events. The organization and method of operation of the machine are described and reasons for the choice of system are discussed. A simplified cor... View full abstract»

  • The application of microelectronics to naval equipment

    Publication Year: 1966, Page(s):309 - 313
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1346 KB)

    The paper first discusses the design criteria for Naval electronic equipment and how far they are satisfied by microelectronics. Equipments for which microelectronics is being considered or is in use are briefly described. Finally some comments are made on the choice of a particular microelectronic technique.

  • The performance of practical constant-resistance modulators in relation to their use in f.d.m. systems

    Publication Year: 1966, Page(s):314 - 318
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (603 KB)

    Ideally modulators with a constant input resistance produce no frequencies across their input terminals other than those impressed by the signal source. They are thus potentially important in simplifying the requirements of filters in multi-channel f.d.m. communication systems, and in the case of double-sideband signals, in eliminating filters since then the modulators can be directly paralleled. ...

  • Analysis of a coupled waveguide circulator using non-reciprocal attenuation

    Publication Year: 1966, Page(s):319 - 323
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (498 KB)

    This paper describes a coupled waveguide circulator in which the secondary waveguide is loaded with distributed non-reciprocal attenuation along the coupling length. In the forward direction of transmission, the difference in the attenuation constants between the two coupled waveguides is large and transmission takes place between the primary waveguide ports. The peak and average power capability ... View full abstract»
