Q174 / 180 · KCET 2010 · Physics

Identify the logic operation performed by the circuit given here.

Correct answer
A
$\mathrm{OR}$
B
NOR
C
NOT
D
NAND

Solution

The given gate circuit is a combination of two NOR gates. $$ \therefore \quad \mathrm{y}=\overline{\overline{\mathrm{A}+\mathrm{B}}}=\mathrm{A}+\mathrm{B} $$ It is boolean expression of OR gate.

Hence, the correct answer is option: 'A'.
