THEORY:- In digital system there are only few basic operations performed, irrespective of the
complexity of the system . These operations may be required to be performed number of times in a
large digital system like digital computer or digital control systems, etc. The basic operations are AND,
OR, NOT, NAND, NOR, EX-OR, EX-NOR. The circuits which perform these operations are called as
GATEs. These GATEs are basic building blocks for any digital circuit.
