Homework Statement
I'm trying to show that the output of this XOR circuit is ##F=A'B+AB'##,
Homework Equations
##(A+B)'=A'\cdot B'##
##(A\cdot B)'=A'+B'##
The Attempt at a Solution
From the gates the output is ##[(A\cdot B)+(A+B)']'##, using De Morgan's laws this becomes ##[(A\cdot B)+(A+B)']'=(A\cdot B)'\cdot (A+B)=(A\cdot B)'\cdot (A+B)=(A'+B')\cdot (A+B)=0##? I can't seem to figure out what I'm doing wrong.
