Vedclass · Answer

(B) logic gate is a fundamental building block of a digital circuit. It is a digital circuit that performs a logical operation on one or more binary inputs and produces a single binary output. The relationship between the input and output is based on certain logical rules,which are represented by Boolean algebra. Common examples include $AND$,$OR$,$NOT$,$NAND$,and $NOR$ gates.
