  Logical NOR - Wikipedia, the free encyclopedia
The logical NOR or joint denial is a boolean logic operator which produces a result that is the inverse of logical or.
The NOR operator is also known as Webb-operation or Peirce arrow, named after Charles Peirce who demonstrated that any logical operation can be expressed in terms of logical NOR.
NOR has the interesting feature that all other logical operators can be expressed by various functions of NOR.

 Logical connective - Wikipedia, the free encyclopedia
In logic, a logical connective is a syntactic operation on sentences, or the symbol for such an operation, that corresponds to a logical operation on the logical values of those sentences.
Logical operators are implemented as logic gates in digital circuits.
The "logical equivalence" of "NAND alone", "NOR alone", and "NOT and AND" is similar to Turing equivalence.

 Logical Argument Narrative @ aNewLow.com (A New Low)   (Site not responding. Last check: 2007-11-03)
In logic, an argument is an attempt to demonstrate the truth of an assertion called a conclusion, based on the truth of a set of assertions called premises.
In ordinary language, people refer to the logic of an argument or use terminology that suggests that an argument is based on inference rules of formal logic.

 Logical fallacy - Wikipedia, the free encyclopedia
In philosophy, the term logical fallacy properly refers to a formal fallacy: a flaw in the structure of a deductive argument which renders the argument invalid.
By extension, an argument can contain a formal fallacy even if the argument is not a deductive one; for instance an inductive argument that incorrectly applies principles of probability or causality can be said to commit a formal fallacy.
Recognizing fallacies in everyday arguments may be difficult since arguments are often embedded in rhetorical patterns that obscure the logical connections between statements.

 Logic (Word Puzzles series) (19 of 29)
All that she wrote was not part of a logical construct, of course, nor did she intend her books to be limited to this approach, but it is precisely her devotion to logic in respect to development of her fundamental propositions which encourages the reader to dwell without prejudice upon the doctrines she transmitted.
Logic is a technique, operable only when some premise has been set forth, but unless one makes use of logic he has no way of knowing which "of all possible premises" offer the most consistent interpretations of experience.
Nor, on the scientific side, did the discovery of certain laws of "natural selection" lead inescapably to the conclusion that the human soul derived its modifications and improvements for the interaction of geographical circumstances and physical adaptability.

 Causation and the Logical Impossibility of a Divine Cause
However, the nomological condition for being a cause is logically inconsistent with a divine cause of the big bang, since God by definition is a supernatural being and his or her actions are not governed by laws of nature.
Principle (1) about causes and logically sufficient conditions implies that no causal conditional is a logical theorem, where a causal conditional has the form "if c occurs, then e occurs" and substitutions for "c" are expressions that refer to the cause and do not include a term for the effect in a referentially transparent context.
Nor can any inductive argument based on the fact that every observed event has a cause be used to support the thesis that the big bang is the result of a divine state, since this inductive argument instead supports the thesis that the big bang is the effect of some cause.

Three-input NOR port This component simulates a second level, two stage logical NOR operator which can be derived using a three-input OR port with an inverted output.
In boolean logic: (A + B + C)' = Q The electrical function of the NOR port mirrors the function of the NOR operator, so that the output of this port is inactive or '0' when at least one of input A *OR* input B *OR* input C is '1'.
In the case of the NOR operator, applying the OR operator and taking the inverse of the output is equivalent to taking the inverse of the inputs and applying the AND operator.

 Field-programmable logic device with programmable foldback to control number of logic levels - Patent 4703206   (Site not responding. Last check: 2007-11-03)
A field-programmable logic architecture is centered on a single array of programmable gates that perform either logical NAND or logical NOR operations.
A device as in claim 1 characterized by internal means for performing at least one logical function on output data from at least one of the gates to generate internal data and for supplying it to at least one of the primary lines exclusive of the input and foldback lines.
In particular, the programmable logic device of the invention employs an array of primary logic gates that operate on data transmitted on a plurality of primary lines.

The received view of logical consequence entails that the logical consequence relation in M turns on the nature of the logical constants in the relevant M-sentences.

Compare with classical logic: the meaning of a logical constant is semantically characterized in terms of its contribution to the determination of the truth conditions of the sentences in which it occurs.

The sync pulse is preferably used as an input to the logical NOR gate 24, because without the sync pulse as an input, there is a possibility for a glitch in the burst gate pulse signal BG at the beginning of the horizontal sync pulse.
When the signal at the node b falls to a logical low voltage level, all of the inputs to the logical NOR gate 24 are at logical low voltage levels and the output BG of the logical NOR gate 24 becomes active and will therefore preferably rise to a logical high voltage level.
When the signal at the node a rises to a logical high voltage level, the output BG of the logical NOR gate 24 becomes inactive and will preferably fall to a logical low voltage level, signalling that the burst signal is no longer present on the composite video signal.
