Problem $8$: Design a combinational logic circuit which has one output $Z$ and a $4-$bit input

ABCD representing a binary number. $Z$ should be $1$ if the input is at least $3$ but is no

greater than $7.$

Step $1$: List truth table:

Step $2$: Get the sum$-$of$-$minterms expression:

$Z(A,B,C,D)=(,)$
