Ans:- In electronics , a logic gate is an idealized or physical device implementing a Boolean function ; that is, it performs a logical operation on one or more binary inputs and produces a single binary output. Q):- How many types of logic gates are there ? Ans:- There are three types of logic gates. 1):- Basic gate. 2):-. Universal gate. 3):- Arithmetic gate./ special gate. 1):- What is Basic gate ? And:- These gates gives idea about one of the fundamental expression either addition of variable , Multiplication of variable and Compliment of the variable. How many types of Basic gate are there ? And:- There are three types of basic gate . a):- NOT gate / inverter . b):- AND gate . C):- OR gate . a):- What is NOT gate ? Ans:- Function of NOR gate is to reverse the nature of the
