    Although proposed in 1961, the nullator and norator have not been widely used or understood. At first sight these elements appear rather remote from reality, and in this paper an attempt is made to relate them to some practical devices. It is suggested that a nullator-norator pair (nullor) may be regarded as a reasonable idealization of a number of physical devices, but that the nullator and norat... View full abstract»

    This paper discusses applications where automatic testing can be a requirement, some of the advantages and disadvantages to both manufacturer and customer, and the demands its use makes upon the aircraft electronic equipment designer. Some of the problems which exist at present are due to the lack of consideration given to the use of automatic testing by the equipment designer. These can be overco... View full abstract»

  • Design of simple frequency-division-multiplex communication systems without band-pass filters, with particular reference to the use of constant-resistance modulators

    Publication Year: 1967, Page(s):277 - 288

    Consideration is given to the design problems of low-cost f.d.m. systems which achieve economy by the avoidance of band-pass filters for each channel at both ends of the system. It is shown that the best basis of design is the use of constant-resistance modulators. View full abstract»

  • V.H.F. field strength measurements over medium length land paths

    Publication Year: 1967, Page(s):289 - 303

    Field strength measurements were made over several overland transmission paths on Bands I and II, at distances up to 274 km. The measurements when corrected for transmitting aerial height above mean terrain and also for receiving site variation factor give field-strength/distance curves which are in reasonable agreement with the current C.C.I.R. tropospheric propagation curves. The range of fading... View full abstract»

  • The application of automation of assembly and testing in computer manufacture

    Publication Year: 1967, Page(s):305 - 319
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1887 KB)

    The layout and construction of a typical second-generation digital computer is outlined, and an account given of the manual methods of assembly and testing in use until comparatively recently. The feasibility of introducing automation techniques is discussed, and an analysis made of those areas of production and testing most amenable to such treatment. Three applications are described, demonstrati... View full abstract»
