    This paper deals with some of the problems encountered in a hybrid simulation of the motion of aerospace vehicles. These problems arise principally from the position of the analog-digital interface and the sampling, which of necessity occurs there, and introduces phase lags that can severely affect the validity of any simulation. The introduction of two redundant integrators can effectively decoup... View full abstract»

    This paper presents tables of all-pass rational transfer functions that approximate a time delay ¿ to within an error ¿ for frequencies ¿ such that 0¿¿¿¿¿. The coefficients are optimized to maximize the bandwidth ¿, if the order n of the transfer function and the maximum error ¿ are predetermined by the user. Two sets of tables are given, corresponding to two different error criteria: 1)... View full abstract»

    Methods of operating standard switching circuits in a Pulsed Power Circuit (PPC) mode in order to reduce power consumption and system complexity are discussed. The PPC concept involves gating the power supply ''on'' for short clocked time intervals. An interesting feature of the system is that multiple power clocks allow multiple numbers to be stored in the same circuits simultaneously. View full abstract»

    It is now well understood that the design of the signal distribution systems of high speed digital machines is as important as the design of the circuits themselves. The integrated circuit technology of today is pressing back the frontiers of speed and simultaneously providing more circuitry per unit area. A signal distribution system with suitable electrical characteristics for these high speed c... View full abstract»

  • Computer Simulation of Waveform Distortions in Digital Magnetic Recordings

    When frequency or phase modulation is applied to digital magnetic recording, both peak shift and amplitude variation occur in the readback signals. These distortions are due specifically to pulse crowding, noise, and variation of separation between read head and recording medium. When such waveform distortions are simulated on the digital computer, the results agree well with those obtained from a... View full abstract»

  • Linearity of Sequential Machines

    A sequential machine is defined to be linear if its next-state function and output function are linear transformations from their domains (vector spaces) to their ranges (also vector spaces). It is shown that this definition is equivalent to those given by other authors. Based on this definition, a set of necessary and sufficient conditions for the flow table of a sequential machine to be linear i... View full abstract»

  • Feedback in Synchronous Sequential Switching Circuits

    In this paper we consider minimum feedback loop realizations of synchronous sequential switching circuits. It is shown that any finite state sequential function can be realized as a synchronous sequential circuit with a single feedback loop, or equivalently, as a one-dimensional iterative circuit with one amplifier between stages. Techniques are described which enable us to find such a realization... View full abstract»

    It has been conjectured [1] that the number Rn of threshold functions of n arguments has the limiting form: Limn¿¿ log2 Rn/n2 = const. Bounds previously obtained [2], [3] show that such a constant would have to lie between ¿ and one. In the present note this constant is shown to have a lower bound of ¿.1 The result is extended t...

  • On the Threshold Order of a Boolean Function

    The notion of a threshold function is generalized to a Boolean function of threshold order r. Two characterizations of a Boolean function of threshold order r are presented, which are generalizations of the results of Kaplan and Winder and of Chow, for the case r = 1. Kaplan and Winder's characterization of a threshold function by means of Chebyshev approximation is generalized to a Boolean functi... View full abstract»

    Assume that our technology uses "black boxes" that may be described by a planar figure. (See Fig. 1.) Each "box" has a finite number of inputs ordered in the manner shown in Fig. 1, from top to bottom on the left-hand side of the "box," and one output coming out of the right-hand side of the "box." The output is some function of the input variables. For the purpose of our discussion, the variables... View full abstract»

    In this paper a relationship among distinct Pn+1, cycles, distinct stable maximum transient feedback shift registers of order n+1, and stable feedback shift registers of order n will be presented. In the course of the discussion, two algorithms will be introduced. The first will provide a one-to-one mapping between distinct stable feedback shift registers of order n and distinct stable maximum-tra... View full abstract»

    Adaptive pattern recognizers incorporate approximations to the class probability distributions that improve as a result of cumulative information derived from known inputs. A simple method is outlined in which a stored sample constitutes a set of points in observation-space at each of which the local value of a class's distribution can be estimated cumulatively as known class-members become availa...
