In this experiment, we are going to usea given $8-10-1$ tine multiplexer circuit. As it cah casily predicted from experiment $4\mathrm{.}1,8$ to $1$ multiplexer contains $8$ data input, $3$ solection inputs and $1$ output.

PRPSAB WORK

$1-$ Draw the block diagram of $8$ to $1$ mmliplener.

$2.$ Wite the truth trble ofit.

$3.$ Can we design a comnarator circuit which compares two $2-$bit numbers and dotects which is the bigtion one? In particular, we have two $2-$bit numbers $($say X$1$X$0$ and Y$1$Y$0).$ If X$1$X$0$ is greater or equal to Y$1$Y$0$ the output of the multiplexer should be $1$ and the output should be $0$ otherwise.

$4.$ Write the truth table of the system described above.

S$-$ Design it by using an $8-$t$0-1$ Jine multiplewer $($hint: choose X$1,$ X$0$ and Y$1$ as selection inputs$).$
