Piggybacking

A function that returns a true value when only one of the input values is true. If both values are false or both values are true, the output of the XOR function is false. The XOR (exclusiveOR) gate acts in the same way as the logical “either/or. ” The output is “true” if either, but not both, of the inputs is “true. ” The output is “false” if both inputs are “false” or if both inputs are “true. ” Another way of looking at this circuit is to observe that the output is 1 if the inputs are different, but 0 if the inputs are the same. 0
