Binary addition xor

WebAn XOR gate may serve as a "programmable inverter" in which one input determines whether to invert the other input, or to simply pass it along with no change. Hence it functions as a inverter(a NOT gate) which may be … WebThe last operator, xor is a special operator. It is the english equivalent of "I either __ or __" and the implication is that both cannot happen at the same time. So when we're connecting these in relation to the individual circuit …
