MCQ
The output $y$, when all three inputs are first high and then low, will respectively be
  • A
    $1, 0$
  • B
    $1, 1$
  • C
    $0, 0$
  • $0, 1$

Answer

Correct option: D.
$0, 1$
d
Let inputs $A, B$ and Care given to the circuit.

$Gate-I$ is AND gate, $gate-II$ is $NANO$ gate.

Output $\quad Y=\overline{(A . B . C)}$

when $A=1, B=1, C=1,$ then

$Y=\overline{(1.1) .1}=\overline{1.1}=\overline{1}=0$

when $\quad A=0, B=0, C=0,$ then

$Y=\overline{(0.0) .0}=\overline{0.0}=\overline{0}=1$
