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
$Z =\overline{(A+B) \cdot(A \cdot B)}$

$Y =\bar{Z}=(A+B) \cdot(A \cdot B)$

$Y =A \cdot B$

$\therefore$ It is an $AND$ Gate
