$3-$ A$-)$ Implement the Boolean function $($F$)$ with a $4$ X $1$ multiplexer and two$-$input$-$NOR gates. Connect inputs A and B to the selection lines. The input requirement for the four data lines will be a function of variables C and D$.$ These values are obtained by expressing Fas a function of C and D for each of the four cases when AB $=00,01,10$ and $11.$ B$-)$ Implement the Boolean function with a $8$ X $1$ multiplexer.
