Logic gates are the fundamental building blocks of digital circuits and systems. They perform logical operations on one or more binary inputs to produce a single binary output. Here, we will discuss the symbols and functions of the basic logic gates.
Basic Logic Gates
AND Gate
Symbol: ____ A--| | |AND |-- Y B--|____|
Function: The AND gate outputs 1 only if all its inputs are 1.
Boolean Expression: ( Y = A \cdot B )
Truth Table: A | B | Y --|---|-- 0 | 0 | 0 0 | 1 | 0 1 | 0 | 0 1 | 1 | 1
OR Gate
Symbol: ____ A--| | | OR |-- Y B--|____|
Function: The OR gate outputs 1 if at least one of its inputs is 1.
Boolean Expression: ( Y = A + B )
Truth Table: A | B | Y --|---|-- 0 | 0 | 0 0 | 1 | 1 1 | 0 | 1 1 | 1 | 1
NOT Gate
Symbol: ____ A--| | |NOT |-- Y |____|
Function: The NOT gate inverts its input.
Boolean Expression: ( Y = \overline{A} )
Truth Table: A | Y --|-- 0 | 1 1 | 0
