Hi, I just realized that there are more exercises and explanations in tut 102. Thanks.
On the errata. Is it not that x'y' + xy = 1? as per the compliment rule. If so then the book is right, because the first and the last terms a compliments of each other. But on the other hand, your answer also looks right?
I quickly started to work out some of the exercises in tut102, but came across the following where I get two different answer depending on what route I take.
Tut102, Exercise E.2, page 39
A = 0, B = 1, C = 1 and D = 0.
e) AB' + (B + D)
route 1:
AB' + (B + D) = 0dot0 + (1 + 0) = 0 + 1 = 1
route 2:
AB' + (B + D) = (AB' + B )dot(AB' + D)
distributive = (0 + 1) dot (0 + 0) = 0
I am definitely missing something...
Please help!...
