    The paper presents a fairly concise descriptive account of the millimetric-band waveguide equipment envisaged for operational use in trunk transmission by the British Post Office. It explains how the repeater spacing is chosen and how the circuit capacity could be built up gradually over many years; it also shows how the service requirements of the system will be met. The functions of the various ... View full abstract»

    Increased sophistication ofpresent microprocessors and other l.s.i. devices allows creation of unconventional computer architectures. The work reported here is part of a project concerned with the application of multi-processor architectures to business data processing. An application is considered as a number of interacting functional units. The operation of a system consists of the allocation of... View full abstract»

    The paper reviews the manual, computer-controlled, and computer-based dynamic testing of control systems, and the reasons for the popularity of such tests. It is shown that correlation techniques are necessary in either time or frequency domains in order to reduce uncertainty due to measurement noise. Engineering guidelines for choosing those test measurements, such as spot frequencies and cross-c... View full abstract»

    This paper gives the results of benchmark tests of several different microprocessors. The results are given in terms of speed of execution, size of source program (number of statements) and of memory requirements for the compiled programs. An analysis of these results is given in terms of the microprocessor architectures. View full abstract»

  • Degradation in the efficiency of medium-size parabolic antennas with propagation conditions

    Publication Year: 1977, Page(s):529 - 534

    The results of a simple, short-term experiment suggest that significant errors may arise in the overall design and costing of a communication system where parabolic antennas are employed at the receiver terminal. Under high signal conditions the relative gains of two parabolic antennas of different diameters are in close agreement with the theoretically predicted value. Under low signal conditions...
