MCQ
Which logic gate produces 'LOW' output when any of the inputs is 'HIGH'?
- AAND
- B$OR$
- CNAND
- ✓NOR
✓
Answer
Correct option: D.
NOR
(d) : For NOR gate, $Y=\overline{A+B}$
If $A=1$ and $B=0$ or $A=0$ and $B=1$ or $A=B=1$
$
Y=\overline{1}=0
$
If $A=1$ and $B=0$ or $A=0$ and $B=1$ or $A=B=1$
$
Y=\overline{1}=0
