    The concepts of microprocessor-based digital filter implementation are presented via a case study of a lowpass filter designed using the bilinear z-transform method.Implementation aspects associated with an 8-bit generalpurpose microprocessor-based realization and a singlechip signal processor are discussed and results included.

  • Pseudo-linear operation of second-order phase-locked loops

    Publication Year: 1981, Page(s):429 - 434

    This paper defines a region of operation, calling it the pseudo-linear region, where a phase-locked loop (p.l.l.), behaves essentially in a linear manner. The results obtained for a loop with an active second-order filter suggest a very simple empirical definition for this region as a function of the parameters of the loop (¿, and ¿n), and classifies the regions of operation of the p.l.l., linea...

  • Optimization of access points for automatic test program generation and fault location in large analogue circuits and systems

    Publication Year: 1981, Page(s):435 - 446

    The paper develops a methodology for the automatic test program generation (ATPG) for a large analogue circuit subject to component drifts. An optimization algorithm developed selects the best set of intermediate access points for a.c. and d.c. tests of the circuit. During ATPG, faults are simulated by varying each component over a wide range. Voltages measured at all available nodes are thus used... View full abstract»

  • Min m.i.s. Schottky barrier solar cellsߞa review

    Publication Year: 1981, Page(s):447 - 454
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1319 KB)

    Problems inherent in conventional p-n junction solar cells are discussed. The principle of operation of min m.i.s. solar cells is then described. Among other advantages it is shown that the min m.i.s. solar cells are capable of giving a much higher Voc compared to the p-n junction solarcells. Problems associated with the min m.i.s. solar cells are also discussed. These include the incompatibility ... View full abstract»

    The paper describes various detection processes for a modem that has been designed for operation at 9600 bit/s over the public switched telephone network. The modem is a synchronous serial system, using a 16-point q.a.m. signal, with near-maximum-likelihood detection at the receiver. The detection processes are modifications of a technique that has recently been developed for use with severely dis... View full abstract»
