MCQ
Identify the logic gate given in the circuit :
- A$NAND$ - gate
- ✓$OR$ - gate
- C$AND$ gate
- D$NOR$ gate
✓
Answer
Correct option: B.
$OR$ - gate
b
$\mathrm{Y}=\overline{\overline{\mathrm{A}} \cdot \overline{\mathrm{B}}}$
$\mathrm{Y}=\overline{\overline{\mathrm{A}} \cdot \overline{\mathrm{B}}}$
By De-Morgan Law
$\mathrm{Y}=\overline{\overline{\mathrm{A}+\mathrm{B}}}$
$\mathrm{Y}=\mathrm{A}+\mathrm{B}$
Hence $OR$ gate
