Question
The combination of ‘NAND’ gates shown here under figure, are equivalent to
- An OR gate and an AND gate respectively
- An AND gate and a NOT gate respectively
- An AND gate and an OR gate respectively
- An OR gate and a NOT gate respectively
The correct answer is: An OR gate and an AND gate respectively
For first case, the Boolean expression is, 
hence for OR gate and for second case, the Boolean expression is 
, hence for AND gate.
