3. For the Boolean function F(w, a, y, z) = xy,z + z'y'2+ u'xy wz'y + wxy. a) Obtain the truth table of F b) Draw the logic diagram, using the original Boolean expression. c) Use Boolean algebra to simplify the function to a minimum number of literals. d) Obtain the truth table of the function from the simplified expression and show that it is the same as the one in part (a)
