Two Boolean networks are the same if and only if they have exactly the same number of inputs and outputs corresponding to each input combination. You need to compare the following simple logic networks.

Equivalent to$??$

a$.$Construct a single gate$-$level circuit for the equivalence checking. Label the output as $\backslash ($x $7\backslash )$such that if this new circuit is satisfiable $(\backslash ($x $7=1\backslash )),$the two logic networks are not equivalent. Draw the schematic

b$.$Derive a CNF for this new $7-$variable $(\backslash (\backslash$mathrm$\{$x$\}1,\backslash$mathrm$\{$x$\}2,$x$\_\{3\},\backslash$ldots$,\backslash$mathrm$\{$x$\}7\backslash ))$logic network

c$.$What is the value assignment for the $7$variables if it is satisfiable? If not, simply write down "not satisfiable".
