NOR gate is the series combination of : - Vidyadip

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.
