The usual floating point arithmetic makes error analysis difficult. This paper describes an alternative system which offers a means of analyzing floating point calculations more effectively and which also possesses certain advantages from an equipment standpoint. View full abstract»

• ### Minimal Sum of Products of Sums" Expressions of Boolean Functions

Publication Year: 1958, Page(s):268 - 276
Cited by:  Papers (9)
| | PDF (1409 KB)

The problem of economical synthesis of circuits for digital computers leads to the problem of finding Boolean expressions of minimal length equivalent to a Boolean expression f. Previous authors restricted themselves to sum of products'' expressions; dualizing this gives products of sums.'' The next more efficient step is to find minimal sums of products of sums'' expressions. In this paper,... View full abstract»

• ### A Method for Synthesizing the Waveform Generated by a Character, Printed in Magnetic Ink, in Passing Beneath a Magnetic Reading Head

Publication Year: 1958, Page(s):277 - 282
Cited by:  Papers (2)
| | PDF (901 KB)

When a character printed in magnetic ink passes beneath a magnetic reading head it generates a waveform. A method is described here to determine this waveform from the geometry of the printed character. The character shape is divided into elementary vertical units and the height of these units is then tabulated. A single set of experimental data is obtained in the laboratory by passing a magnetica... View full abstract»

• ### On the Minimum Logical Complexity Required for a General Purpose Computer

Publication Year: 1958, Page(s):282 - 285
Cited by:  Papers (2)
| | PDF (845 KB)

A definition is provided for the term general purpose computer'' (gpc) which is compatible with usage and is analogous to, but distinct from, Turing's definition of a universal computer.'' A gpc is presented in functional and logical design which seems to approximate the minimum complexity consistent with this definition. No specific definition of complexity nor a bound on required complexity ... View full abstract»

• ### Iterative Combinational Switching Networksߞ General Design Considerations

Publication Year: 1958, Page(s):285 - 291
Cited by:  Papers (21)  |  Patents (5)
| | PDF (1244 KB)

An iterative network is a combinational switching circuit which consists of a series of identical "cells" or sub-networks; for example, the stages of a parallel binary adder. A formal design method for iterative networks is presented. This is similar to the flow table technique for designing sequlential circuits. View full abstract»

• ### Some Properties of Boolean Equations

Publication Year: 1958, Page(s):291 - 298
Cited by:  Papers (8)
| | PDF (1236 KB)

Solubility conditions for a set of Boolean equations are established, first with respect to one variable, then with respect to all variables. By consideration of relations between minimal terms, a simple matrix form is deduced for Boolean equations. Using finite group theory and the properties of the characteristic equation of the matrix, a classification is introduced for Boolean mappings and the... View full abstract»

Publication Year: 1958, Page(s):299 - 306
Cited by:  Papers (12)
| | PDF (1268 KB)

Mealy's model of a sequential machine is assumed and a relation of compatibility'' of states is introduced to further the analysis of such machines. In the event that input restrictions exist it is often possible to effect combinations of states under this relation in addition to those permitted under equivalence of states, a relation previously studied. Compatibility of states is analyzed by an... View full abstract»

• ### Theoretical Consideration of Computing Errors of a Slow Type Electronic Analog Computer

Publication Year: 1958, Page(s):306 - 312
Cited by:  Papers (6)
| | PDF (958 KB)

When solving differential equations using analog computers, there are two causes of errors: one results from the integrators and the other results from the coefficient setting elements. The former is independent of the order of the differential equation if the integrating time constants are all equal, while the latter is dependent on the setup procedure. The amount of the error from the coefficien... View full abstract»

• ### BIDEC - A Binary-to-Decimal or Decimal-to-Binary Converter

Publication Year: 1958, Page(s):313 - 316
Cited by:  Papers (10)  |  Patents (2)
| | PDF (819 KB)

Simple, high-speed devices to convert binary, binary coded octal, or Gray code numbers to binary coded decimal numbers or vice versa is described. Circuitry required is four shift register stages per decimal digit plus one 30-diode network per decimal digit. In simple form the conversion requires two operations per binary bit but is theoretically capable of working at one operation per bit. View full abstract»

• ### Diodeless Magnetic Shift Registers Utilizing Transfluxors

Publication Year: 1958, Page(s):316 - 324
Cited by:  Papers (5)
| | PDF (1547 KB)

Shift registers using magnetic cores have been conventionally designed with diodes to provide isolation between stages. It is possible to use transfluxors in a two-core-per-bit fashion so as to provide isolation between stages by magnetic means rather than with diodes. A design procedure for doing so is discussed.
