MCQ
$\text{NOR}$ gate is the series combination of :
- A$\text{NOT}$ gate followed by $OR$ gate.
- ✓$OR$ gate followed by $\text{NOT}$ gate.
- C$\text{AND}$ gate followed by $OR$ gate.
- D$OR$ gate followed by $\text{AND}$ gate.
✓
Answer
Correct option: B.
$OR$ gate followed by $\text{NOT}$ gate.
Truth table of $\text{NOR}$ is complement of $OR$. That's why $\text{NOR}$ is combination of $OR$ gate followed by $\text{NOT}$ gate.
