Digital Gates
Digital gate is a Digital Device used to perform the logic operation on the input(s) to produce an equivalent logic in the output. The output produced from the inputs are listed in a table called a Truth table. The relation between output and inputs can also be represented by a mathematic equation.

There are 5 basic digital gates used to perform Logic Operation namely /Buffer/, /NOT/, /AND/, /OR/, /XOR/
