Problem $6(15$pts$)$

In class we built an ALU which is simply a device that performs a logical operation on the inputs. The operation that is performed is based on the selection of the operational switches.

Draw a circuit for an ALU that has one bit inputs A and $B,$ and that has output as defined in the following table.

$\backslash$table$[[$S$1,$S$0,$Output$],[0,0,$A or B$],[0,1,$A or B$],[1,0,$A plus B $($ignore the carry$)],[1,1,$Pass through A$]]$
