I have a quick question about some Boolean algebra.
The problem is:
F (A, B, C) = A + B
And I want to expand it into canonical-sum form. The problem is there is no 'C' so I am unclear on how to do it. Normally, I would find the min-term and go from there, however, the min-term has C in it. I would appreciate any help.
Hint: $$A+B=A(B+\bar B)(C+\bar C)+B(A+\bar A)(C+\bar C)$$ Expand this expression, get rid of duplicates and you are done.
