    A design philosophy for transistorized analog computing amplifiers is presented. A design procedure for a summing amplifier to drive a specific resolver in a 400 cps system is described, and the performance of the resulting circuit is evaluated. Whereas experience with vacuum tube amplifiers in similar applications has led to the conclusion that the amplifier input impedance should be as large as ... View full abstract»

    Several corrections are given to a recent tabulation of two-terminal contact networks realizing the switching functions of four variables. Nineteen new networks which are more economical in contacts than those previously tabulated are also presented and certain four-variable functions possessing a useful complementary relationship are listed. In conclusion this paper indicates an area where furthe... View full abstract»

  • On the Loop- and Node-Analysis Approaches to the Simulation of Electrical Networks

    The number of integrators in an analog-computer setup should be equal to the order of the differential equation describing the system. This paper presents a new procedure for tracing the loop currents which results in one-to-one correspondence between the number of integrators in the stimulation setup and the count of independent energy-storing elements in the network, i.e., the degree of the syst...

  • Generalized Parity Checking

    Publication Year: 1958, Page(s):207 - 213
    Cited by:  Papers (20)

    The usual definition given for the parity check is unwieldy and not particularly suited for the analysis or the study of the arithmetic properties of parity checking. The definition of parity by means of congruences provides a convenient mathematical basis for the concepts of the parity check. In this paper congruence notation is used to generalize the concepts of parity to include nonbase two num... View full abstract»

  • Investigations of magnetic amplifiers with feedback

    Publication Year: 1958, Page(s):213 - 217
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (685 KB)

    Sine wave carrier excited magnetic amplifiers have been investigated to determine if the figure of merit can be improved through the use of feedback techniques. It is shown that the power gain can be made unlimited but that a finite rise time is preserved. Hence the figure of merit as ordinarily defined becomes meaningless. It is shown, however, that voltage gain divided by rise time remains nearl... View full abstract»

  • A New Class of Digital Division Methods

    This paper describes a class of division methods best suited for use in digital computers with facilities for floating point arithmetic. The division methods may be contrasted with conventional division procedures by considering the nature of each quotient digit as generated during the division process. In restoring division, each quotient digit has one of the values 0,1, . . . , r -1, for an arbi... View full abstract»

  • Magnetic Core Pulse-Switching Circuits for Standard Packages

    Publication Year: 1958, Page(s):223 - 228
    Cited by:  Papers (5)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1215 KB)

    A new method for the logical design of magnetic core pulse-switching circuits is presented. This method has features which make it excellent for use in standard packages. These features are the absence of spurious noise signals at the output; the fact that outputs are independent of the order of arrival of input pulses; the fact that interchanging components does not affect circuit behavior; and t...

  • The Switching Characteristics of 4-79 Permalloy Cores with Different Anneals

    Publication Year: 1958, Page(s):228 - 231
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (658 KB)

    The magnetic properties of 4-79 Permalloy cores, which have been annealed at different temperatures, are discussed. Cores annealed at relatively low temperatures are characterized by high coercivity, slower switching, insensitivity to strain, magnetization difficult to rotate, and insensitivity to an applied transverse field. Some cores exhibit a preference to one remanent state over the opposite ... View full abstract»

  • Formal Analysis and Synthesis of Bilateral Switching Networks

    Cited by:  Papers (7)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2132 KB)

    Formal procedures for the analysis and synthesis of two-terminal combinational bilateral switching networks are presented. A bilateral switching network is one which contains only elements having the same switching transmission characteristic in both directions. Following the definitions for the terminology and notation, where some new terms are introduced, the definitions for a series-parallel ne... View full abstract»

  • A Transistor Pulse Generator for Digital Systems

    A design procedure is developed for a new transistor pulse generator circuit suitable for use as a building block in a digital system. The circuit produces a pulse whose shape is relatively independent of variations in transistor parameters and load current. Pulse durations in the range 0.5 microsecond to 20 microseconds and load currents of several hundred milliamperes may be obtained. View full abstract»
