- logic state
- The logical sense, true or false, of a given binary signal. A binary signal is a digital signal that has only two valid values. In physical terms the logical sense of a binary signal is determined by the voltage level or current value of the signal, and this in turn is determined by the device technology. In TTL circuits, for example, a true state is represented by a logic 1, approximately equal to +5 volts on a signal line; logic 0 is approximately 0 volts. Voltage levels between 0 and +5 volts are considered undefined. Since only two logic states, logic 1 and logic 0, are possible, the techniques of Boolean algebra may be used to analyze digital circuits involving binary signals. The term positive logic is applied to circuits where logic 1 is assigned to the higher voltage level; in negative logic circuits a logic 1 is indicated by the lower voltage level. See also multivalued logic

It seeks to systematize the abstract, purely conceptual relations between propositions in this sphere, such as the following: If an act is obligatory, then its performance must be permitted and its omission forbidden. In given circumstances, every act is such that either it or its omission is permitted. Modal logic leaves to substantive disciplines such as ethics and law the concrete questions of what specific acts or states of affairs are to be forbidden, permitted, or the like

- fuzzy logic
- A form of algebra employing a range of values from "true" to "false" that is used in decision-making with imprecise data, as in artificial intelligence systems. a type of logic which is used to try to make computers think like humans. Logic based on the concept of fuzzy sets, in which membership is expressed in varying probabilities or degrees of truth that is, as a continuum of values ranging from 0 (does not occur) to 1 (definitely occurs). As additional data are gathered, many fuzzy-logic systems are able to adjust the probability values assigned to different parameters. Because some such systems appear able to learn from their mistakes, they are often considered a crude form of artificial intelligence. The term and concept date from a 1965 paper by Lotfi A. Zadeh born 1921 . Fuzzy-logic systems achieved commercial application in the early 1990s. Advanced clothes-washing machines, for example, use fuzzy-logic systems to detect and adapt to patterns of water movement during a wash cycle, increasing efficiency and reducing water consumption. Other products using fuzzy logic include camcorders, microwave ovens, and dishwashers. Other applications include expert systems, self-regulating industrial controls, and computerized speech-and handwriting-recognition programs

- fuzzy logic
- Fuzzy logic provides an approach to approximate reasoning in which the rules of inference are approximate rather than exact Fuzzy logic is useful in manipulating information that is incomplete, imprecise, or unreliable Also called fuzzy set theory, fuzzy logic extends the simple Boolean operators, can express implication, and is used extensively in Artificial Intelligence (AI) programs Fuzzy logic allows computers to work more easily with phrases such as "fairly," "rarely," or "almost " It allows computers to use more than just true or false
- fuzzy logic
- A number of financial variables involved if financial decision are, but their very nature, fuzzy We talk about high price/earning stock Well, what is high?

- logic
- A particular kind of logic is the way of thinking and reasoning about things that is characteristic of a particular type of person or particular field of activity. The plan was based on sound commercial logic. Study of inference and argument. Inferences are rule-governed steps from one or more propositions, known as premises, to another proposition, called the conclusion. A deductive inference is one that is intended to be valid, where a valid inference is one in which the conclusion must be true if the premises are true (see deduction; validity). All other inferences are called inductive (see induction). In a narrow sense, logic is the study of deductive inferences. In a still narrower sense, it is the study of inferences that depend on concepts that are expressed by the "logical constants," including: (1) propositional connectives such as "not," (symbolized as ), "and" (symbolized as ), "or" (symbolized as ), and "if-then" (symbolized as ), (2) the existential and universal quantifiers, "(x)" and "(x)," often rendered in English as "There is an x such that ..." and "For any (all) x, ...," respectively, (3) the concept of identity (expressed by "="), and (4) some notion of predication. The study of the logical constants in (1) alone is known as the propositional calculus; the study of (1) through (4) is called first-order predicate calculus with identity. The logical form of a proposition is the entity obtained by replacing all nonlogical concepts in the proposition by variables. The study of the relations between such uninterpreted formulas is called formal logic.

Computers perform calculations using components called logic gates, which are made up of integrated circuits that receive an input signal, process it, and change it into an output signal. The components of the gates pass or block a clock pulse as it travels through them, and the output bits of the gates control other gates or output the result. There are three basic kinds of logic gates, called "and," "or," and "not." By connecting logic gates together, a device can be constructed that can perform basic arithmetic functions

- {i} modern system of logic that uses abstract symbols to represent quantities and relationships
- modal logic
- Formal systems incorporating modalities such as necessity, possibility, impossibility, contingency, strict implication, and certain other closely related concepts. The most straightforward way of constructing a modal logic is to add to some standard nonmodal logical system a new primitive operator intended to represent one of the modalities, to define other modal operators in terms of it, and to add axioms and/or transformation rules involving those modal operators. For example, one may add the symbol L, which means "It is necessary that," to classical propositional calculus; thus, Lp is read as "It is necessary that p." The possibility operator M ("It is possible that") may be defined in terms of L as Mp = Lp (where means "not"). In addition to the axioms and rules of inference of classical propositional logic, such a system might have two axioms and one rule of inference of its own. Some characteristic axioms of modal logic are: (A1) Lp p and (A2) L(p q) (Lp Lq). The new rule of inference in this system is the Rule of Necessitation: If p is a theorem of the system, then so is Lp. Stronger systems of modal logic can be obtained by adding additional axioms. Some add the axiom Lp LLp; others add the axiom Mp LMp

- A specialized device used to provide high-speed, low-level control of a process It is programmed using LD or some form of structured language, so that engineers can program it PLC hardware typically costs a lot of money, and often has very good redundancy and fail-over capabilities When you walk around a factory, the thing with all the lights and buttons and switches is the PLC (or possibly a DCS, which is a big PLC)
- programmable logic controller
- A digital controller used for applications such as on/off control, timing, logic, counting and sequencing
- programmable logic controller
- (Ticaret) (PLC) A device using programmed, custom instructions to provide automated monitoring and control functions by evaluating a set of inputs. Used to automate complex functions in machining, packaging, materials handling or other applications

- propositional logic
- a branch of symbolic logic dealing with propositions as units and with their combinations and the connectives that relate them
- simple logic
- easy way of understanding something
- symbolic logic
- any logical system that abstracts the form of statements away from their content in order to establish abstract criteria of consistency and validity
- symbolic logic
- A treatment of formal logic in which a system of symbols is used to represent quantities and relationships. Also called mathematical logic
- symbolic logic
- {i} mathematical logic, modern system of logic that uses abstract symbols to represent quantities and relationships
- variable logic
- A form of internal machine logic that may be changed to match programming formats
