I've just started studying computer engineering, and I'm having some doubts regarding the behavior of the XOR gate.
I've been projecting circuits with Logisim, whose XORs behave differently from what I've learnt. To me, it should behave as a parity gate, giving a high output whenever the inputs receives an odd combination. It doesn't, though, for more than two inputs. How should it behave?
I also read in a book that XOR gates are not produced with more than two inputs. Is that correct? Why?
