    The output behaviour of multiple-output combinational circuits in response to stochastic inputs is examined with the help of Walsh functions. The joint error probabilities at the output can be determined from the input statistics by jointly considering two inputs: a noise-free signal and the same signal corrupted by independent additive noise. For the case of signal and noise components which are ... View full abstract»

    With the introduction of cheap programmable l.s.i. components, the designer of digital systems has a great deal of flexibility in implementation, especially in producing multiprocessor systems. To produce cost-effective designs, he needs the ability to design in an implementation-independent manner and then to map this abstract design onto the cheapest hardware-software system consistent with the ...

    The concavity tree (c.t.) is an attractive way of representing the shape of a 2-dimensional object or silhouette. In this paper, the literature on the subject is briefly reviewed, the method of generating c.t.s is described and their properties discussed. The paper goes on to report original work on the use of c.t.s for matching shapes and for detecting certain features such as edge features and s... View full abstract»

  • Study of the use of microprocessors in digital filtering

    Publication Year: 1979, Page(s):169 - 176
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (879 KB)

    In this paper, the application of microprocessors to digital filtering has been considered. To achieve the highest possible working frequencies when using microprocessors it has been found necessary to employ the method of distributed arithmetic. A new computational formulation is introduced which leads to methods of implementation which allow for better signal/roundoff-noise ratios at the expense... View full abstract»

  • Controlling a vector-multiplier-based digital filter by using a microprocessor

    Publication Year: 1979, Page(s):177 - 181

    Using a vector multiplier, in conjunction with a Motorola M6800 microprocessor, a digital filter section has been implemented. The implementation has added flexibility to the vector multiplier as well as giving sampling rates in the region of 20 000 samples/s. View full abstract»

  • Developments of the iterative digital cellular multiplier

    Publication Year: 1979, Page(s):181 - 182
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (276 KB)

    This note briefly describes functions which can be performed by some developments of iterative r.o.m.-based multipliers and similar systems. It substantially extends the work reported in our earlier letter, which itself extended the iterative digital cellular r.o.m.-based multiplier of Chung and Bedrosian. Details of the earlier extension, and of the new work, may be found in an NPL Report, the pu... View full abstract»

Aims & Scope

Published from 1978-1979, the IEE Journal on Computers and Digital Techniques (CDT) was a quarterly journal that was devoted to digital systems in the broadest sense, covering the structure, design and technology of the systems themselves and the subsystems and components from which they are built.
