    The incidence of complaints of r.f. interference from industrial, medical and scientific equipment is examined in the light of the acceptable limits set by international and national regulations. Some of the compromises which can be struck between the desirable and the practicable are illustrated by examples. View full abstract»

  • A review of fault detection methods for large systems

    Publication Year: 1976, Page(s):276 - 280

    A critique is made of current research into practical fault finding procedures for the maintenance of complex engineering systems. The half split and other methods currently in practice are analysed and their main weakness shown to be that no account is taken of the various costs involved. Also analysed are cost conscious methods which are useful in diagnosis training or in designing fault detecti... View full abstract»

    The current state of the art in liquid crystal displays and the characteristics of other newly-developed displays, particularly electrophoretic and electrochromic devices, are discussed. The advantages and disadvantages of the different types of displays for particular applications are examined. The new liquid-crystal phase-change, guest-host system and the electrophoretic display appear to have a... View full abstract»

  • Microwave amplification and phase shifting with impatt diodes

    Publication Year: 1976, Page(s):296 - 298

    The gain-phase responses of × band amplifying impatt diode phase shifters have been experimentally investigated. The design procedure is described for a gallium arsenide diode for which 180° phase shifts were obtained with gains of 7.5 dB. The power handling capability of the phase shifter is limited by the incidence of parametric oscillation due to the non-linear inductance associated with the ... View full abstract»

  • An experimental delta-modulation transversal filter for compression of chirp data-signals

    Publication Year: 1976, Page(s):299 - 311
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1844 KB)

    The paper examines the application of the deltamodulation transversal (d.m.t.) pulse-compression filter for chirp signal generation and processing in chirp-signal data communication systems. The d.m.t. filter is compared in this respect with the lumpedcomponent dispersive network. Details are given of the design, construction and operation of an experimental pulse-compression d.m.t. filter. The fl... View full abstract»
