MCQ
The logic operations performed by the given digital circuit is equivalent to:
- ✓$AND$
- B$NOR$
- C$OR$
- D$NAND$
✓
Answer
Correct option: A.
$AND$
a
$Z =\overline{(A+B) \cdot(A \cdot B)}$
$Z =\overline{(A+B) \cdot(A \cdot B)}$
$Y =\bar{Z}=(A+B) \cdot(A \cdot B)$
$Y =A \cdot B$
$\therefore$ It is an $AND$ Gate
