    This paper describes measurements of frequency spectrum and amplitude of 5 GHz signals reflected from large, generally flat, building faces. Two techniques were used, namely dynamic (i.e. fast moving transmitter source) and static, with ground-based equipment located near an aircraft runway. Although simple theoretical considerations had suggested that the reflection characteristics should be appr... View full abstract»

    This paper follows on from the previous paper in the series and attends to the methodology of design as conceived within the whole-system whole-life dimensions of systems engineering. It assumes the concepts and general structure of systems engineering as outlined in the previous paper and goes on to elaborate the form and content of systems engineering from a design perspective. The paper begins ... View full abstract»

    A cellular array for the multiplication of signed binary numbers is presented. The implementation is based on the direct addition of the partial products. The addition of the negative partial products is performed with a new method which yields a fully cellular array. Furthermore, the proposed array multiplier has an iterative cell interconnection pattern and it is well suited for large-scale inte... View full abstract»

  • Synchronization of 6.3 mm tape recorders using EBU time and control code

    Publication Year: 1981

    The paper discusses the addition of EBU time and control code to the twin-track format on 6.3 mm tape recorders. The code is carried on a centre track 0.8 mm wide using a recording characteristic of zero microseconds so that the system can read the code accurately over a wide range of tape speeds. To preserve the waveshape, the recording amplifier has phase-corrected equalization; and to minimize ... View full abstract»
