Let's say I have a boolean expression, such as F1 = x'y' ⊕ z .
How do I go about finding the minterm list for that expression?
The method I've tried is to take each term, such as x'y' and z, then fill in the missing values with all possibilities. So for x'y' there exists two options of 00- where z is 000 and 001. Then for Z it's --1, where the values can be 001, 011, 101, 111. So the minterms would come out to be 0, 1, 1, 3, 5, and 7.
My method of finding them, however, is wrong, because the minterms are actually 0,3,5, and 7.
What's the appropriate method to obtain the minterm list in this situation?
