Two identical low-pass electrical filters, having any realizable low-pass frequency-response characteristic and synthesized from linear analog computer components by any convenient method, may be interconnected in a simple manner to form a band-pass filter whose frequency-response characteristic represents a translation along the frequency axis of the frequency response characteristic of the origi...

Cited by:  Papers (5)
| |PDF (1479 KB)

This paper develops a theory of symmetric ternary switching functions and presents systematic methods for their detection, identification and synthesis. Shannon's theory of binary symmetric functions is extended to ternary functions by defining a set of five priming'' operations which, together with the permutation'' operations, form a group. Algebraic characterizations of totally and partiall... View full abstract»

• ### Feedback in Asynchronous Sequential Circuits

Publication Year: 1966, Page(s):740 - 749
Cited by:  Papers (31)
| |PDF (1755 KB)

In this paper we attempt to realize any flow table of a desired sequential circuit so as to minimize the feedback index (number of feedback loops) of the resulting asynchronous sequential switching circuit. It is shown that any flow table M, which describes the circuit action of a normal fundamental mode asynchronous sequential circuit, can be realized as a fundamental mode circuit with feedback i...

The display system discussed in this paper was implemented to provide a flexible test bed for man-machine interaction. The discussion includes both hardware and software design concepts, and concludes with an evaluation of the system based on operating experience. The two significant organizational features of the hardware are 1) the sharing of memory between a normal computer and a special pictur... View full abstract»

• ### Analysis of Programs for Parallel Processing

Publication Year: 1966, Page(s):757 - 763
Cited by:  Papers (108)  |  Patents (2)
| |PDF (1234 KB)

A set of conditions are described which determine whether or not two successive portions of a given program can be performed in parallel and still produce the same results. The conditions are general and can be applied to sections of the program of arbitrary size. The conditions are interesting because of the light they shed on the structure of programs amenable to parallel processing and the memo... View full abstract»

| |PDF (1555 KB)

This paper classifies error correcting codes for arithmetic and provides the necessary and sufficient conditions for the various code classes. Particular attention is given to the arithmetic properties of the codes. It is shown that the Brown codes and the Henderson codes are examples of a general class of nonseparate, nonsystematic codes. Henderson's systematic code is shown to be the only system... View full abstract»

• ### Pattern Recognition with Three Added Requirements

Publication Year: 1966, Page(s):770 - 781
| |PDF (2095 KB)

A number of additional constraints are added to the usual problem of forming a pattern recognition scheme using adaptive techniques. These require that the system formed be 1) capable of adding a new class without requiring excessive change of the original structure, 2) able to handle sequential patterns as generated by events which occur over a period of time, and 3) able to predict parts of the ...

• ### Cobalt-Substituted γ-Fe2O3 as a High-Density Recording Tape

Publication Year: 1966, Page(s):782 - 793
Cited by:  Papers (2)
| |PDF (1969 KB)

In this study we investigated the recording performance of a surface composed of Co-substituted γ-Fe2O3 particles. These particles were cubic in shape with edge length of 500 to 1000 Å, and coercivity of 500 to 600 Oe. This high coercivity is due primarily to the large magnetocrystalline anisotropy of the cobalt cation in the spinel lattice. The recording surf... View full abstract»

The behavior of nonlinear viscoelastic materials to low velocity impacts is described in terms of simple mathematical models which take into account the effects of nonlinear damping and deflection characteristics. An approximate analytical solution is given for the particular case of an impact printer (a typical piece of computer peripheral equipment). An expression for the impact contact time''...

A study of the output of a heuristic computer program reveals two four-state binary Turing machines which yield the highest known score for four states in Rado's co-called "Busy Beaver" logical game. There is evidence which supports the conjecture that this score of 13 is the particular value of Σ(4), where Σis a noncomputable integer function associated with this game. It is also ...
