1. The problem statement, all variables and given/known data This is from a past exam paper for logic design in my course. I have an exam coming up and would love to know how to solve this one. Develop a circuit realization of the XOR function with three inputs. You may use AND, OR and NOT-gates with not more than two inputs. Either draw the circuit or (for simplicity) write down the exact equivelant Boolean Expression with correctly positioned parenthesis 2. Relevant equations DeMorgans Law...I think... 3. The attempt at a solution I have not really gotten anywhere with this one. NAND and NOR functions with three inputs worked out fine for me, but not this one. For DeMorgans you have to: Change all variables to their complements. Change all AND operations to ORs. Change all OR operations to ANDs. Take the complement of the entire expression. So how does this one work with XOR? (A xor B xor C) = (A'B + AB') AND C - this seems off.. I am not even sure if im moving in the right direction. If anyone could lay out the steps in how to do this one I would appreciate it.
