    In examining flip-flop response the principal concern of the logical designer is to find what input signals must be applied to the flip-flop in order to produce the output conditions that are desired. Equation methods of analysis and a time-sequential tabular method of analysis are described, and some advantages of the tabular method are pointed out. View full abstract»

  • Dynamic Accuracy as a Design Criterion of Linear Electronic-Analog Differential Analyzers

    Publication Year: 1957, Page(s):74 - 86

    A frequency error analysis of computing elements is presented which leads to a definition of their dynamic accuracy. The concept of a computing transfer function is introduced for this purpose, permitting the evaluation of an effective bandwidth, the latter being connected with the variance of the output for wideband inputs. Limited bandwidth is considered as equivalent to finite resolution and th... View full abstract»

  • Trigonometric Resolution in Analog Computers by Means of Multiplier Elements

    Publication Year: 1957, Page(s):86 - 92

    A method of generating sine and cosine functions in analog computers by means of multiplier elements and integrators is discussed. Static accuracy of the method is analyzed and found to be essentially equal to the accuracy of the multipliers employed. The system accepts d¿/dt as the input and generates output voltages of sin¿ and cos ¿. Amplitude-stabilizing loops are employed to maintain sin2Â... View full abstract»

    A transfer tree is a particular type of multiterminal network having a single input which may be connected to any one of a number of outputs. An n-relay transfer tree is partially developed if it has less than the 2n possible output terminals. Rearrangement of a partially-developed tree can lead to a reduction in the total number of transfers required. This paper presents a method of obtaining a r... View full abstract»

    With the diode function generators that are currently in use, generation of functions is made by combining straight lines, The main drawback of these function generators is that the slope of the line segment cannot be changed independently. With the new function generator described in this paper, functions are generated by connecting independent line segments. Accordingly, the slope of each segmen... View full abstract»

  • An Electronic Analog Multiplier

    Publication Year: 1957, Page(s):100 - 103
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (769 KB)

    This multiplier uses the variable pulse area principle, but employs phase sensitive circuitry to operate naturally in all four quadrants without bias voltages. The output is zero if either input is zero. The X and Y channels are separately linearized with independent feedback loops. The circuitry is simple and lends itself to either transistors or vacuum tubes. View full abstract»

  • An Algorithm for Determining Minimal Representations of a Logic Function

    For each logic function, or Boolean algebraic expression, there corresponds an appropriate computer circuit. However, the minimization of the appearances of the Boolean variables does not necessarily lead to the most economical circuit. A general approach to the problem therefore requires the development of techniques for the simple and rapid generation of a variety of near-minimal forms. This pap... View full abstract»

    This paper describes novel calculating techniques suitable for an electronic analog computer using exponential discharges to simulate the logarithmic scales of the slide rule. Among others, the device can perform the following operations: z = xy; z = x/y; z = xya; loga x; az; and evaluate such series as y = Axa + Bxb +Cxc+ ... where the exponents can be fractional and z, x, and y can be time varia...
