MCQ
Which logic gate is represented by the following combination of logic gates
  • A
    $OR$
  • B
    $NAND$
  • $AND$
  • D
    $NOR$

Answer

Correct option: C.
$AND$
c
(c)$Y = \overline {\bar A + \bar B} $
According to De morgan’s theorem
$Y=\overline{\bar{A}+\bar{B}}=\bar{\bar{A}}.\bar{\bar{B}}=A.B$
This is the output equation of $‘AND’$ gate.
