• ### On the Efficient Assignment of Internal Codes to Sequential Machines

Publication Year: 1962, Page(s):611 - 622
Cited by:  Papers (20)
| | PDF (2213 KB)

A set of procedures for assigning codes to internal states of a synchronous sequential machine so as to minimize the internal logic in two-level form is proposed. The procedures are based on interpreting the state table of a sequential machine as a set of mappings from present states into next states, under control of the inputs. Attention is focused on a particular subset of these mappings, calle... View full abstract»

• ### Disjunctively Linear Logic Nets

Publication Year: 1962, Page(s):623 - 639
Cited by:  Papers (4)
| | PDF (2981 KB)

Three notions are introduced: 1) a class of logic nets with disjunctively linear structure,'' 2) disjunctively linear behavior'' or logic nets, and 3) position diagrams'' to represent logic nets. Through the study of their properties, it is shown that there is a close relationship between disjunctively linear structures and the behavior of logic nets. It is then shown that the state diagrams... View full abstract»

• ### The Synthesis of Boolean Functions Using a Single rrhreshold Element

Publication Year: 1962, Page(s):639 - 642
Cited by:  Papers (21)
| | PDF (661 KB)

The synthesis of a threshold element which realizes a desired Boolean function as its output may be accomplished by solving a basic set of linear inequalities. The determination of this basic set is discussed with the aid of a geometric interpretation of such realizable functions on the vertices of a unit N cube. A solution may be obtained to these inequalities by linear programming. In this paper... View full abstract»

• ### Design of a Repairable Redundant Computer

Publication Year: 1962, Page(s):643 - 649
Cited by:  Papers (9)  |  Patents (1)
| | PDF (1351 KB)

The design of a repairable redundant computer is discussed using the Von Neumann multiplexing scheme. The general considerations, as well as the reasons for selecting this type of redundancy, are given. A reliability model of the redundant equipment is presented with resulting curves for estimating the reliability improvement and the additional cost of the redundant equipment. The mean time betwee... View full abstract»

• ### An Automatic Self-Checking and Fault-Locating Method

Publication Year: 1962, Page(s):649 - 654
Cited by:  Papers (1)
| | PDF (2067 KB)

A method is described for designing systems which automatically check themselves and give indications by which internal faults can be located quickly and accurately. Relatively little circuitry is required, and the performance of the test and fault location are easy. The proposed method entails the arrangement of a sequence of events which can be completed properly only if no malfunction exists. A... View full abstract»

• ### Coding for Multiple Asymmetric Errors in One Channel of a Multichannel System

Publication Year: 1962, Page(s):655 - 658
| | PDF (731 KB)

An efficient error correction code for correcting errors of one kind in an arbitrary N-character message is discussed. The coded check character is obtained by summing the weighted coded characters (columns of binary digits where each binary digit assumes a unique weight) within an entire record modulo a prime integer. This check character is then added to the record before transmission over a cha... View full abstract»

• ### A New Approach to Resistor-Transistor-Tunnel-Diode Nanosecond Logic

Publication Year: 1962, Page(s):658 - 664
Cited by:  Papers (3)
| | PDF (3952 KB)

A transistor amplifier with nonlinear tunnel-diode or backward-diode feedback is described for use as a resistor-coupled threshold logic circuit or general purpose switch. The tunnel-diode feedback serves to virtually eliminate saturation and prevent cutoff thus allowing the high gain-bandwidth products of epitaxial switching transistors to be utilized at all times during switching. Switching plus... View full abstract»

• ### Flux Reversal in Three-Rung Laddics

Publication Year: 1962, Page(s):664 - 676
Cited by:  Papers (2)
| | PDF (3085 KB)

When the flux in the driven branch of a multipath core is reversed most of it will return via the shortest return path in the core. A small fraction will return by the next shortest. The ratio of the flux change in the shortest path to that in the next shortest is called the branching ratio r. Experimental branching ratios are much larger than they reasonably should be. In this paper a magnetic ci... View full abstract»

• ### Improving the Performance of the Sense-Amplifier Circuit Through Pre-Amplification Strobing and Noise-Matched Clipping

Publication Year: 1962, Page(s):677 - 683
Cited by:  Papers (4)
| | PDF (1464 KB)

For the improvement of the performance of the sense-amplifier circuit for conventional ferrite-core memories, the principles of pre-amplification strobing and noise-matched clipping are proposed and discussed. A circuit incorporating these principles and achieving notable reliability and economy is described. The circuit is suitable for working with short cycle times and low signal-to-noise ratio ...

• ### A Recognition Method Using Neighbor Dependence

Publication Year: 1962, Page(s):683 - 690
Cited by:  Papers (39)
| | PDF (1434 KB)

Within the framework of an early paper1 which considers character recognition as a statistical decision problem, the detailed structure of a recognition system can be systematically derived from the functional form of probability distributions. A binary matrix representation of signal is used in this paper. A nearest-neighbor dependence method is obtained by going beyond the usual assumption of st... View full abstract»

Cited by:  Papers (4)
| | PDF (1410 KB)

It is shown in this paper how a straightforward solution to the regression problem can be obtained for continuous variables on a general-purpose analog computer. The linear case (least squares straight line) is thoroughly described. A specific nonlinear problem, that of estimating the parameters of a missile trajectory, is also described. The regression equations are derived and analog computer ci... View full abstract»

• ### Obtaining the Internal Junction Characteristics of a Transistor for Use in Analog Simulation

Publication Year: 1962, Page(s):709 - 710
| | PDF (348 KB)

A technique is described for making the internal base-to-emitter junction characteristics of an alloy junction transistor available to an analog computer simulation process. This is accomplished with an active feedback network that continuously compensates for the internal voltage drop across the extrinsic base-spreading resistance at all base current levels.
