2. Recall that an XOR gate is a digital logic gate that gives a true (1) output when the
two inputs are different, and false (0) otherwise. An equivalent XOR function with
inputs A and B can be implemented in Excel 2010 using the formula:
a) = AND(OR(A,B), NOTAND(A,B)))
b) =A<>B
c) = NOT(NOT(A<>B))
d) EAND(NOT(AND(A,B)), OR(A, B))
e) All of the above x
