a) Write a Boolean equation in sum-of-products canonical form for each of the truth tables below. Note that sum-of-products canonical form means that each product should include all four variables. (a) (b) 0 (e) B TOO Y 1 B 0 B 0 1 0 1 (c) 0 0 0 0 Y 1 0 1 1 Y 1 D 0 1 1 1 OOO OHOHOHO OOOOO BcY 1 1 0 1 1 1 1 0 1 1 1 1 0 1 1 1 lo OOO 1 1 1 1 1 1 C D Y 1 1 1 1 0 0 0 0 (d) B 0 0 0 0 0 1 0 1 0 1 0 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 1 QlOOOOOO 1 1 O OOOOOOO OOOOOOOOO- OOOOHH OOOO 1 0 1 1 OOOOH 1 1 0 0 1 1 0 0 1 1 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 OOOOOOOO 1 0 1 0 1 OOOO 1 1 0 1 0 1 1 b) Express all five canonical forms as a sum of minterms (e.g. m + m2 + ms). c) Express all five canonical forms as a product of maxterms
