Introduction and design procedure

Introduction-

In digital circuit theory, combinational logic (sometimes also referred to as  combinational circuits) is a type of digital logic which is implemented by Boolean circuits, where the output is a pure function of the present input only.Whereas in sequential circuits , the output depends on present state of input and previous states of input. In other words, sequential logic has memory while combinational logic does not.
