1. An electronic switch that is the elementary component of a digital circuit. It produces an electrical output signal that represents a binary 1 or 0 and is related to the states of one or more input signals by an operation of Boolean logic, such as AND, OR, or NOT. Also called: logic gate. See also gate array.
2. The input terminal of a field-effect transistor (FET). Also called: gate electrode. See also drain (definition 1), FET, MOSFET, source (definition 2). 3. A data structure used by 80386 and higher microprocessors to control access to privileged functions, to change data segments, or to switch tasks.

Množina reči logic circuit je logic circuits.
An electronic circuit that processes information by performing a logical operation on it. A logic circuit is a combination of logic gates. It produces output based on the rules of logic it is designed to follow for the electrical signals it receives as input. See also gate (definition 1).
In electronics, see logic gate.
Or logic circuit; In electronics, one of the basic components used in building integrated circuits. The five basic types of gate make logical decisions based on the functions NOT, AND, OR, NAND (NOT AND), and NOR (NOT OR). With the exception of the NOT gate, each has two or more inputs.
Information is fed to a gate in the form of binary-coded input signals (logic value 0 stands for “off” or “low-voltage pulse”, logic 1 for “on” or “high-voltage”), and each combination of input signals yields a specific output (logic 0 or 1). An OR gate will give a logic 1 output if one or more of its inputs receives a logic 1 signal; however, an AND gate will yield a logic 1 output only if it receives a logic 1 signal through both its inputs. The output of a NOT or inverter gate is the opposite of the signal received through its single input, and a NOR or NAND gate produces an output signal that is the opposite of the signal that would have been produced by an OR or AND gate respectively. The properties of a logic gate, or of a combination of gates, may be defined and presented in the form of a diagram called a truth table, which lists the output that will be triggered by each of the possible combinations of input signals. The process has close parallels in computer programming, where it forms the basis of b
