$(5$pt$)$ We construct a $2-$bit multiplier using Mux

as following. Two inputs are provided to a

selector in Mux. For instance, $01**01=0001$ and

$00**00=0000$ in the following figure. Fill the

remained constant input values in the Mux to

complete the multiplier. $(15$pt$)(5$pt$)$ We construct a $2-$bit multiplier using Mux as following. Two inputs are provided to a selector in Mux.
