Q 12-14-128JEE MainJEE Main 2021 (31 Aug, Shift 1)Easy
In the following logic circuit the sequence of the inputs $A$, $B$ are $(0, 0)$, $(0, 1)$, $(1, 0)$ and $(1, 1)$. The output $Y$ for this sequence will be:
Answer: (C) $1, 1, 1, 0$
$P = AB$, $Q = A + B$, $Y = \overline{P\cdot Q}$.
$(0,0)$: $P = 0$, $Q = 0$, $Y = 1$
$(0,1)$: $P = 0$, $Q = 1$, $Y = 1$
$(1,0)$: $P = 0$, $Q = 1$, $Y = 1$
$(1,1)$: $P = 1$, $Q = 1$, $Y = 0$
