Is there any way to simplify a combination of XOR and XNOR gates in the following expression? I have tried multiple boolean theorems and I have not been able to simplify this any further:
The simplified version is
XOR(A,B)*XNOR(C,D) + XOR(C,D)*XNOR(A,B)
The actual expression is:
(A'B + AB')(CD + C'D') + (AB + A'B')(C'D + CD')
According to my lab, this expression can be simplified, but I don't know where to start.
I guess you could look at each element, such as
(A'B + AB') as a single variable, such as X and then the equation would be
XY' + X'Y, but I still don't see how to simplify that.
