| | PDF (1852 KB)

One of the most important and complicated problems in the synthesis of a sequential machine described by a state diagram or table is the assignment of the states of the secondary variables to the states of the machine. The secondary assignment for a given machine varies in accordance with the requirements of the design. It has already been shown that the partition with the substitution property an...

The organization and reliability of large redundant nets of formal neurons are investigated. Each neuron has m inputs and n outputs and is capable of performing at any one time any member of any prescribed subset of the total possible set of 22mÂ·n functions. Various methods for obtaining large nets of predictable structure and function through the medium of element reproduction are dis... View full abstract»

• ### Analysis of Linear Sequential Circuits by Confluence Sets

Publication Year: 1964, Page(s):226 - 231
Cited by:  Papers (14)
| | PDF (1051 KB)

In this paper the group-theoretical concept of confluence sets'' is introduced as a valuable tool in the analysis of linear sequential circuits (LSC's). Using this concept, a scheme is formulated for producing state graphs of autonomous LSC's which, in the singular'' case, is superior to currently known schemes. Singular LSC's, which are of potential interest in error correction systems, are s... View full abstract»

• ### A Method for Testing and Realization of Threshold Functions

Publication Year: 1964, Page(s):232 - 239
Cited by:  Papers (20)
| | PDF (1317 KB)

A standard method for testing and realizing a threshold function is to solve a set of linear inequalities in which the unknowns are the n weights to be assigned to the n variables. In this paper a simple method of solving this set of inequalities is presented. Instead of using the weights themselves as the unknowns, a set of n new unknowns, the incremental weights Δa1, Δ...

| | PDF (2091 KB)

During the past few years there has been a considerable amount of literature concerned with the realization of threshold logic. However, there are a number of questions concerning such factors as sensitivity and component savings which cannot be completely answered by such theoretical studies. DONUT (Digitally Operated Network Using Thresholds) is a small general purpose digital computer which was... View full abstract»

A brief description of the logical structure and the instruction repertoire of a short word length (16 bits) computer is given. The unorthodox features which are discussed are 1) a variable-length addressing procedure, 2) a common multi-accumulator and index register structure, and 3) the identical processing of data and addresses.

• ### A Quantising Encoder

Publication Year: 1964, Page(s):250 - 254
| | PDF (966 KB)

A device is described that converts voltages to digital form by means of a strategy basically faster than that used in the conventional trial encoder. A voltage corresponding to the contents of a 2n-bit register is obtained from the output of the digital-voltage decoder. The error between this voltage and the input voltage is quantized to the nearest power of two and subtracted from the contents o... View full abstract»

Commercially available magnetic tape units have longitudinal recording densities of up to 2000 bits per inch, whereas analog instrumentation recorders are capable of recording up to 10,000 cycles per inch. These figures contrast with a theoretical recording density limitation for iron oxide of 250,000 bits per inch, and the reasons for this discrepancy are analyzed. Two experimental systems having...

• ### Flux Divison in a Saturable Multipath Core

Publication Year: 1964, Page(s):272 - 277
| | PDF (856 KB)

An mmf drive NI is applied to the major leg of asaturable ferrite core whose three legs are initially at negative saturation. The resulting Δø in the driven leg divides into the other two (minor) legs, one of which is loaded by a resistive load. This division of flux is analyzed, using for each leg the parabolic inelastic switching model ø = øpeak (F) [1-... View full abstract»

| | PDF (1300 KB)

A simple experiment on a magnetically-balanced circuit, consisting of a flux source and two equal-length parallel paths is outlined. It is observed that if a controlling signal causes one of the parallel paths to be preferred and this controlling signal is removed before switching is completed, the parallel path originally preferred continues to be preferred. The core equivalent of a balanced circ... View full abstract»
