Q$7-$ A combinational circuit is specified by the following Boolean expressions.

$F_1(x,y,z)={\displaystyle \underset{?}{\overset{?}{}}}(0,2,4)$

$F_2(x,y,z)={\displaystyle \underset{?}{\overset{?}{}}}(1,3,7)$

$F_3(x,y,z)={\displaystyle \underset{?}{\overset{?}{}}}(2,4,5,6)$

Implement the combinational circuit with a decoder. NAND or AND gates are connected

to the output of decoder.
