Logic Gates

Logic gates are the basic elements that make up a digital system. The electronic gate is a circuit that is able to operate on a number of binary inputs in order to perform a particular logical function. The types of gates available are the NOT, AND, OR, NAND, NOR, exclusive – OR, and the exclusive – NOR.

Note : EX– OR and EX – NOR gates are also known as mutually exclusive gates.
