Consider the function: $F(x,Y,Z)=\stackrel{}{x}Z+\frac{x}{b}ar(Z)+xY.$

a$.$ Draw the logical diagram of the function F$.(4$ marks$)$

b$.$ Using only NAND gates, represent each term in the function: $\stackrel{}{x}Z,\frac{x}{b}ar(Z),$ and $xY.$

$(6$ marks$)$

c$.$ Draw the logical representation of the function $F$ by assembling the equivalent

NAND terms that you have found part b$.(5$ marks$)$
