    A logical design theory for ternary voltage switching circuits is developed. The theory is based on familiar binary switching circuit elements and simplification methods. The theory thus leads to simple electronic realization. The basic system of ternary switching elements consists of function realizable by means of either diode gates or a single triode (transistor).

    A graphical interpretation of the realization of symmetric Boolean functions with threshold logic elements is presented, from which a systematic synthesis method is developed. Theoretically, symmetric functions of any number of variables can be realized. Examples are given to show that, practically, there is no difficulty at all in realizing symmetric Boolean functions of as many as thirty or fort... View full abstract»

    A new computing element is described in which binary numbers are added by means of analog techniques. It is shown that when this element, which will be called a quantiser, is used, the design of arithmetic units for digital computers is considerably simplified. In particular, it is possible to build simple parallel adders and multipliers which do not require any external programming and which may ... View full abstract»

    The disturbed incremental magnetization changes that accompany the read and write operations of coincident-current memories are the cause of a serious noise problem in the attainment of high-speed memory performance. This paper examines the noise problem. Relationships which express the memory driver tolerances in terms of the core characteristics are presented; the operating schmoo is evolved and...

    An analytical method of designing recognition functions in self-organizing systems is discussed in this paper. A mathematical model is defined which embodies recognition and learning processes based on past experiences. The ``desired function'' is introduced as the most faithful expression of recognition functions based on past experiences, and it is shown how to design the recognition function wh...

  • The Solution of Lagrange's Equations by Analog Computation

    A procedure for solving Lagrange's equations of motion by analog computation is discussed. The problem of summing loop instabilities is minimized because the coefficient matrix of the acceleration terms in the generalized force equations is positive definite. No computer instabilities occur if external generalized forces do not contain acceleration-dependent terms (from rubbing friction). A two-di... View full abstract»

    R.M. Karp, author of "Some Techniques of State Assignment for Synchronous Sequential Machines," which appeared on pages 507-518 of the October, 1964, issue of these Transactions, notes corrections on page 511, column 1, line 36, and on page 517, "(2a)-(2d)" should be replaced by "a, b, c, and d" in the following places: column 1, 5 lines from the bottom, column 2, lines 1-2, line 25, and line 28.

    Threshold functions and statistical recognition have been the subjects of many papers and, although the threshold functions have frequently been used as a logic implementation in empirical studies of pattern recognition [1], most, if not all, of the reported theoretical investigations treat these two subjects separately. The purpose of this paper is to present an equivalence between threshold func... View full abstract»

    In the design of registers for controlling a digital process, it is often desired to count through a sequence of specified length and terminate the count by returning to the initial state. A penalty is associated with the use of a straightforward binary code for such counters because of the large number of diodes required to implement the counter, and because of the pyramiding effect which heavily...

    The memory we describe here is a logical and practical outgrowth of the content addressable distributed logic memory of Lee and Paull.1 However, there are several significant differences: the inclusion of a "match" flip-flop and a "control" flip-flop in each cell of the memory, the addition of a "Mark" line to activate many cells simultaneously, and the control of the propagation of the marking si...

    Logic circuits composed of NOR or NAND elements are now being used extensively in digital systems, mainly because of their economy; one type of element may be used throughout an entire circuit. Assuming that the basic decision to use such "universal" elements has been made, the main design objective will usually be to produce either the fastest or the most economical circuit possible. The fastest ... View full abstract»

    One of the more promising areas of computer use involves the coupling of a man to a computer system for real-time problem-solving where the procedure for solution of the problem is either unknown or involves complex tasks, such as pattern recognition, that can best be performed by humans [1]. Unfortunately, a straightforward approach to such use commits significant amounts of computer time most of... View full abstract»

    Cantor, Estrin and Turn have described a special-purpose structure to implement sequential table look-up (STL) algorithms for the evaluation of ln x and exp x.1 Tables of precomputed constants are used to transform the argument into a range where the function may be approximated by a simple polynomial. The transformation for ln x, originally proposed by Bemer,2 is where the set of constants ai are... View full abstract»

    An on-line man-computer program has been described and experimental results concerning the demands made upon the computer are reported. For this particular system it would appear unwise to attempt a time-sharing with other programs on most systems. The use, however, as a single multicomponent program is quite reasonable. It is felt that the functions that are defined and measured here are sufficie... View full abstract»
