Logic Gate

( also gate ) ( computing 计) an electronic switch that reacts in one of two ways to data that is put into it. A computer performs operations by passing data through a very large number of logic gates .

integrated circuit

 a small microchip that contains a large number of electrical connections and performs the same function as a larger circuit made from separate parts

NOT Gate

Whenthe input is LOW the output is HIGH and when the input is HIGH the output is LOW.

非门

AND Gate

HIGH if all of the inputs are HIGH, LOW in all other cases.

与门

NAND Gate

A NAND gate is a NOT AND gate

与非门

OR Gate

LOW if all of the inputs are LOW, HIGH if any of the inputs are HIGH.

或门

NOR Gate

A NOR gate is a NOT OR gate

或非门

XOR Gates

XOR: HIGH if one input or another input (not both) is high.

异或门

XNOR Gates

XNOR =  NOT XOR

Boolean expression

In computer science, a Boolean expression is an expression in a programming language that produces a Boolean value when evaluated, i.e. one of true or false. A Boolean expression may be composed of a combination of the Boolean constants true or false, Boolean-typed variables, Boolean-valued operators, and Boolean-valued functions.[1]

Boolean expressions correspond to propositional formulas in logic and are a special case ofBoolean circuits.[2]
