For the following circuits, first complete the truth table, and then write the Boolean equation for

output $Z$ based on the completed truth table. Write both the sum$-$of$-$products and product$-$of$-$sums.

Sum$-$of$-$products $Z_1$ :

Product$-$of$-$sums $Z_1$ :

Sum$-$of$-$products $Z_2$ :

Product$-$of$-$sums $Z_2$ :
