    A digital system design language, DDL, has been described and shown to provide a concise yet precise means of specifying the organization and operation of digital systems, regardless of timing mode or hardware types, at various levels of detail [2]. This paper defines a series of tasks that transform any DDL document to Boolean and next-state equations from which a system may be implemented. Each ... View full abstract»

    This paper is concerned with the sign detection problem in residue number systems. The proposed solution is applicable only to nonredundant systems. It is shown that under rather general conditions an explicit, closed formula for the sign function can be obtained. In a special case, when one of the moduli is 2, the sign function becomes an EXCLUSIVE-OR function. A sign detection algorithm is propo... View full abstract»

    A method of decision making which leads to the formation of a gain vector by utilizing a design set of patterns from only the class to be recognized is proposed. Some comparisons of this method with the adaline technique have been made and the method has been applied to the practical problem of speaker verification. View full abstract»

    This paper is concerned with a general approach to the on-line simulation of block-diagram systems. These systems may be analog, digital, or hybrid; memory or memoryless; explicit or implicit (i.e., possessing loops of memoryless elements); vector or scalar; or of a more specialized nature, such as dynamic systems with integrators as memory elements; and simulation may be conducted in one or more ...

  • Fuzzy Logic and its Application to Switching Systems

    Fuzzy logic deals with propositions which may be ascribed values between falsehood and truth (0 and 1) subjectively in either a continuous or a discrete fashion. This is in contrast to ordinary logic (two-valued or k-valued logic) in which a given proposition is ascribed values objectively using either deterministic or probabilistic approaches.

  • Real-Time Computation by n-Dimensional Iterative Arrays of Finite-State Machines

    Publication Year: 1969, Page(s):349 - 365
    Cited by:  Papers (94)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3040 KB)

    An n-dimensional iterative array of finite-state machines is formally introduced as a real-time tape acceptor. The computational characteristics of iterative arrays are illuminated by establishing several results concerning the sets of tapes that they recognize. Intercommunication between machines in an array is characterized by specifying a stencil for the array. The computing capability of the a... View full abstract»

    Recognition experiments have been performed on handprinted characters using a set of features which has not been applied previously to handprinting. Glucksman's "characteristic loci" were utilized in experiments with the well-known Highleyman data, as well as samples generated at Stanford Research Institute and Honeywell. Two recognition algorithms were tested. Results on numeric samples compare f... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (824 KB)

    Seven methods are compared for deriving approximate realizing weights and threshold for a threshold function, given its Chow parameters. These include use of the parameters themselves, methods published by Dertouzos and the author, and several new methods. The comparison is made over all seven-argument self-dual threshold function types, and establishes a certain "geometric rule" as best. One thir... View full abstract»

    Placing a fixed resistor in parallel with an adjustable resistor will cause the resistance of the combination to vary as the logarithm of the setting of the adjustable resistor over a limited range. Calculated compromises between accuracy and range cover ±0.1 percent over a 2.5:1 range to ±10 percent over a 175:1 range. A table of intermediate values is given. View full abstract»
