    Abstract—This paper deals with theoretical and experimental aspects of estimating correlation functions of signals generated by nonstationary processes. The estimation process is based on approximation of the expectation or ensemble average definition of the correlation function. The assumption of stationarity regarding the signals under analysis need not be made. Emphasis is placed on off-l... View full abstract»

  • An Approximation to the Asymmetric Strip-Line Coupling Coefficient

    Publication Year: 1968, Page(s):537 - 542

    Abstract—In the design of magnetic film memories and high-speed printed wiring systems, it is often necessary to estimate the coupling between adjacent conductors which are, in effect, strip lines with asymmetric ground planes. No solution to this problem exists in the literature. An heuristic approximation is found, and validated experimentally, which allows a very simple calculation (over ... View full abstract»

  • A Simple High-Speed Magnetic Access Switch Matrix

    Publication Year: 1968, Page(s):542 - 550

    Abstract—An improved switch core principle is described which can be applied to a pulsewidth as short as 50 ns. The factors usually limiting switch core performance, such as pulse distortion due to low field strength, heat, and noise are eliminated by the use of long, thin permalloy needles. These needles can easily be provided with coils with a large number of turns and thus high field stre... View full abstract»

    Abstract—The magnetic second-harmonic analog memory is a device capable of performing the functions of an integrator and an analog memory. The device consists of two magnetic cores wound in such a way that an output voltage of even-harmonic relationship to a drive voltage is produced having an amplitude proportional to remanent core flux. In the following paper, device performance and fundam... View full abstract»

  • Synthesis of Asynchronous Sequential Circuits with Multiple-Input Changes

    Abstract—A frequently imposed restriction in theoretical treatments of asynchronous sequential circuits is that only one input variable be allowed to change during a transition. In this paper, we present three methods for realizing asynchronous sequential circuits allowing multiple-input changes, but requiring that all input changes associated with an input transition be completed within a s...

  • Minimal Multiplexed Threshold Gate Realizations

    Publication Year: 1968, Page(s):566 - 578
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2112 KB)

    Abstract—In this paper, methods are presented for designing error-correcting capabilities into threshold gate networks so that the logic gates themselves will correct errors of other gates in the network . In all but one of these methods, a given realization is modified by the addition of redundant gates to obtain an error-correcting network . Realizations are obtained by the first three met...

  • Bounds on the Period of Oscillatory Activity in Randomly Interconnected Networks of Neuron-Like Elements

    Publication Year: 1968, Page(s):578 - 591

    Abstract—Repetitious activity is assumed in randomly interconnected networks of elements with spacial and temporal summation of input excitation and exponentially decaying threshold and stimulation. Bounds on the period of that oscillatory activity are theoretically established, and verified by computer simulation. The dependency of such bounds on threshold and stimulation decay rates, numbe...

  • A Two-Rail Cascade Synthesis of Boolean Functions

    Abstract—A simple synthesis procedure has been derived for the simultaneous realization of two arbitrary binary functions of the same 4 variables in a single two-rail cascade. The synthesis method is based on successive transformations of the given table of functions into the table realizable by a 2-cell cascade. Usable transformations relate to 13 classes of 2-input, 2-output networks, a li... View full abstract»

    Abstract—A number of techniques exist for realizing completely symmetric switching functions.1 Completely symmetric switching functions are particularly simple and economical to realize using contact-type gating elements. This paper shows that any switching function can be transformed to a completely symmetric switching function in which some of the arguments are redundant. (Obviously, if a ... View full abstract»

  • Generalized Parallel Redundancy in Digital Computers

    Abstract—Triple modular redundancy becomes common when applications place a high premium on the reliability of a digital computer . As the weight, volume, and cost of electronic components decrease, 5-, 7-, or 9-fold redundancies should be considered. This short note presents expressions on the reliabilities of a general n-fold redundant system. View full abstract»

  • On the Motion of an Unbounded, Markov Queue in Random Access Storage

    Abstract—A particular method for storage of first-in-first-out queues in random access memory is analyzed. The storage scheme gives minimum overhead costs at the expense of storage utilization. The resulting queue is analyzed as a Markov chain and the stationary, joint probability distribution is obtained for the queue length and the relative location of the head of the queue. Expressions fo... View full abstract»
