Cited by:  Papers (13)  |  Patents (2)
| | PDF (1477 KB)

This paper is divided into two parts. In the first part, the basic tunnel diode logic circuits are discussed. These include the monostable and the bistable analog-threshold gates and the Goto-pair,'' which uses the principle of majority decision. These circuits are studied to determine the requirement on tunnel diodes and other component tolerances. Relations between the fan-in'' and the fan... View full abstract»

• ### Transistor Current Switching and Routing Techniques

Publication Year: 1960, Page(s):302 - 308
Cited by:  Papers (2)
| | PDF (1855 KB)

A system of circuit logic is described in which transistors, particularly diffused base transistors, are operated well out of saturation in order to make the most of their speed. Logical information is contained in the presence or absence of a current which can be switched or routed by the gates described. Also described is the application of this system of logic to certain specific computer probl... View full abstract»

• ### Magnetic film memories, a survey

Publication Year: 1960, Page(s):308 - 314

| | PDF (1435 KB)

An analysis is made of the modes of magnetization reversal and rotation in thin ferromagnetic films. The ways in which the various modes can be employed for destructive and non-destructive memories are discussed and their performance limitations considered. Existing film memory efforts are partially surveyed and the material and system problems are examined. Possible future developments are also d... View full abstract»

• ### Some Applications of Magnetic Film Parametrons as Logical Devices

Publication Year: 1960, Page(s):315 - 320
Cited by:  Papers (7)  |  Patents (1)
| | PDF (1008 KB)

High-frequency magnetic film parametrons have been made and observed to exhibit two- or three-state operation for a single bias condition. As a two-stable-state device, the magnetic film parametron can be used as a majority decision element in much the same way as the ferrite core parametron. Another useful logical two-state device is a threshold element, in which the input excitation must reach a... View full abstract»

• ### A Thin Magnetic Film Shift Register

Cited by:  Papers (14)
| | PDF (1307 KB)

An initial application of the dynamics and interactions of domains within continuous magnetic thin film structures is made to a shift register in which binary information is stored and translated in and along a continuous evaporated thin magnetic film. These thin magnetic film shift registers are capable of storing information having a density of several hundred bits per square inch of vacuum evap... View full abstract»

• ### FluxlokߞA Nondestructive, Random-Access Electrically Alterable: High-Speed Memory Technique Using Standard Ferrite Memory Cores

Publication Year: 1960, Page(s):323 - 328
Cited by:  Papers (5)
| | PDF (2460 KB)

The Fluxlok memory technique uses the principle of cross-field magnetization to achieve the nondestructive sensing of the information state of standard, readily available, ferrite memory cores in a simply wired memory plane. Bipolar output (ONE and ZERO) signals are obtained at the rate of rise of the READ pulse. The signals are unaffected by test temperatures of from ߝ65Â°C to +100Â°C. Coin... View full abstract»

• ### Magnetostrictive Ultrasonic Delay Lines for a PCM Communication System

Cited by:  Papers (2)
| | PDF (1378 KB)

A servo-operated delay-line pad and a temperature-compensated delay-line memory, both magnetostrictively driven at 1.5 mc, have been used in an experimental PCM communication system.1 The delay-line pad automatically compensates for external delay changes as small as plus or minus 8 mÂ¿sec at a rate of 75 mÂ¿sec second. The delay-line memory stores 192 bits which are available serially with an acc... View full abstract»

• ### Error Detecting and Correcting Binary Codes for Arithmetic Operations

Publication Year: 1960, Page(s):333 - 337
Cited by:  Papers (57)  |  Patents (1)
| | PDF (739 KB)

The most important property of the codes derived in this paper is that two numbers, i and j, have coded forms, C(i) and C(j) that when added in a conventional binary adder, give a sum C(i)+C(j) that differs from C(i+j), the code for the sum, by (at most) an additive constant. This makes possible the detection and/or correction of errors committed by the arithmetic element of a computer. In additio... View full abstract»

• ### A Theorem for Deriving Majority-Logic Networks Within an Augmented Boolean Algebra

Publication Year: 1960, Page(s):338 - 342
Cited by:  Papers (30)
| | PDF (790 KB)

Recent developments in computer technology have produced devices (parametrons, Esaki diodes) that act logically as binary majority-decision elements. Conventional design techniques fail to utilize fully the logical properties of these devices. The resulting designs are extravagant with respect to the number of components used and the operating time required. This paper reviews the conventional tec... View full abstract»

• ### The Use of Parenthesis-Free Notation for the Automatic Design of Switching Circuits

Publication Year: 1960, Page(s):342 - 352
Cited by:  Papers (3)
| | PDF (1944 KB)

A parenthesis-free notation is introduced for the representation of series-parallel switching networks. The notation facilitates the calculation of circuit parameters and permits an unambiguous characterization of the circuit topology. Given certain criteria for feasibility of a switching network related to the circuit parameter values, it is shown how an infeasible series-parallel network can be ... View full abstract»

The equivalent input circuit representation for dc misalignment (offset) has appeared in the literature for the special case of a vacuum tube voltage amplifier with infinite input impedance. This paper will generalize the concept of the equivalent input circuit representation for dc offset for the four amplifier types with finite input impedances, and will give the conditions under which the use o...

If the ac signal at the "cosine" terminal of a sine-cosine resolver (or synchro transmitter connected to a transformer so as to perform the function of a sine-cosine resolver) is fed back to the rotor through an amplifier of suitable gain, the signal at the sine'' terminal can be made proportional to rotor rotation for angles up to 90/spl degrees/ or greater. A theoretical analysis of the relati... View full abstract»

As simulation studies grow more elaborate and complex, the computer operator is confronted with an ever increasing number of problems not directly associated with the study at hand. This paper describes a specially designed computer for solving the coordinate transformation equations normally encountered in a six degree of freedom simulation study. This computer expands the capabilities of present... View full abstract»
