Identify the logic operation performed by the circuit given here.
- A \(\mathrm{OR}\)
- B NOR
- C NOT
- D NAND
Answer & Solution
Correct Answer
(A) \(\mathrm{OR}\)
Step-by-step Solution
Detailed explanation
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.
\[
\therefore \quad \mathrm{y}=\overline{\overline{\mathrm{A}+\mathrm{B}}}=\mathrm{A}+\mathrm{B}
\]
It is boolean expression of OR gate.
