a. ABC’ + (ABC’)’ b. (AB+CD’)(AB+D’E) c. A + B’C + D’(A+B’C) d. AB’(C+D) + (C+D)’
2) Multiply out to obtain a sum of products a. (A+B)(A+C’)(A+D)(BC’D+E) b. (A+B’+C)(B’+C+D)(A’+C)
3) Factor each to obtain a product of sums a. AB + C’D’ b. A’BC + EF + DEF’
4) Last HW we determined the output for each of the circuits
Now, simplify each equation.
