Abstract
Abstract A voter circuit with averaging means eliminates a deadzone characteristic inherent in prior art voter circuits when unvoted or unwanted input signals are near zero. Elimination of the deadzone characteristic renders the voter usable in small signal regions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
149 words
Apparatus voting on a plurality of input signals for providing an output signal, comprising: a plurality of amplifier means, each of which receives one of the plurality of input signals at a first input terminal and provides an output signal at an output terminal; other amplifier means connected at a first input terminal to the output terminal of each of the plurality of amplifier means and connected at an output terminal to a second input terminal of each of the plurality of amplifier means, and voting on the plurality of input signals for providing the output signal at said output terminal; and means connected to the output terminals of each of the plurality of amplifier means and to the first input terminal of each of the plurality of amplifier means for averaging the plurality of input signals over a predetermined range, with the voting occurring outside of said range.
Claim 2
Dependent Claim
149 words
Apparatus voting on a plurality of input signals for providing an output signal, comprising: a plurality of amplifier means, each of which receives one of the plurality of input signals at a first input terminal and provides an output signal at an output terminal; other amplifier means connected at a first input terminal to the output terminal of each of the plurality of amplifier means and connected at an output terminal to a second input terminal of each of the plurality of amplifier means, and voting on the plurality of input signals for providing the output signal at said output terminal; and means connected to the output terminals of each of the plurality of amplifier means and to the first input terminal of each of the plurality of amplifier means for averaging the plurality of input signals over a predetermined range, with the voting occurring outside of said range.
Claim 3
Dependent Claim
78 words
Apparatus as described by claim 1, wherein the means connected to the output terminal and to the first input terminal of each of the plurality of amplifier means for averaging the plurality of input signals over a predetermined range includes: a plurality of resistors, each of which is connected to the output terminal and to the first input terminal of a corresponding amplifier means of the plurality of amplifier means for applying local feedback to said amplifier means.
Claim 4
Dependent Claim
