    “Our generation is being called upon to bury the past,” said Léonce Montambault, chairman and chief executive officer of Bell Canada, as he started his keynote address at the 1989 conference of the Canadian Society for Electrical and Computer Engineering in Montreal last September. “In just a few years we have cast aside most of the technologies that served us well in a...

  • SAW devices for communications applications

    Publication Year: 1990, Page(s):97 - 100
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (805 KB)

    The market for surface acoustic wave (SAW) devices now exceeds $100 million. The author presents an overview of the different SAW device structures available and summarizes their properties. He then describes a number of applications related to the communications industry, including general bandpass filters, Nyquist filters, clock recovery filters, packaging labels and Fourier transformers.

    The authors describe a study of combined Barker codes for application in radar systems. The use of tap weighting with an inverse ripple filter to reduce autocorrelation sidelobes in combined Barker codes is also discussed. The implementation of biphase and quadraphase combined Barker codes using surface acoustic wave (SAW) devices is given as an example. View full abstract»

  • High-speed Viterbi decoder memory design

    Two initial designs are presented to highlight some of the problems encountered in high-speed Viterbi memory design and to illustrate that a pointer-based path-history storage/retrieval system reduces the number of interconnections between memory cells and makes efficient use of path history memory. Unfortunately, this process suffers from the need for a large increase in clock frequency, which ap... View full abstract»

  • The distribution of lightning strokes to towers and along the span of shielded and unshielded power lines

    Publication Year: 1990, Page(s):115 - 122

    A knowledge of the distribution of lightning strokes to towers and along the span of shielded power lines is needed to refine the outage rate calculation method. Such information is also needed for unshielded line because the outage mechanism differs depending on whether the stroke terminates on a tower or on a live wire. The authors provide the needed information based on a 3-D representation of ... View full abstract»

  • Electronically tunable microstrip combline filter

    The authors present the design of a fast, electronically tunable microstrip combline filter. Packaged GaAs tuning diodes are employed as the tuning elements. The design incorporates the results of experimental varactor characterization. Thus, the package and mounting parasitic effects are adequately estimated. Tapped line input and output matching circuits are proposed to compensate for the effect... View full abstract»
