Question $46($Mandatory$)(2$ points$)$

The Boolean equation for the exclusive$-$OR function is

$x\frac{?}{b}=ar(AB)+AB$

$x\frac{?}{b}=ar(A)B+\frac{A}{b}ar(B)$

$x\frac{?}{b}=ar(A)B\frac{+}{b}ar(AB)$

$x\frac{?}{b}=ar\frac{A}{b}ar(B)+AB$

Question $49($Mandatory$)(2$ points$)$

When the output of the NOR gate S$-$R flip$-$flop is $Q=0$ and $\frac{?}{\text{b}\text{a}\text{r}}(Q)=0,$ the inputs are

$S=1,R=0$

$S=1,R=1$

$S=0,R=0$

$S=0,R=1$
