It is possible to have n?input AND, or, NAND, and NOR gates, where n > 2. Can you have an n?input XOR gate for n > 2? Explain your answer with a truth table.
What will be an ideal response?
You can have AND, OR, NAND, and NOR gates with any number of inputs. They obey the rules of the simple 2? input gates (e.g., the output of a NAND gate is true if and only if each of its n inputs are true simultaneously).
The exclusive or gate is rather more complex. If you define it as a gate with two inputs whose output is true if one or both inputs are true, then you can have only a 2?input EOR (XOR) gate. However, if you say that the output of an XOR gate is y = a?b, then you can also have y = a?b?c?d. In this case the output is true if the number of inputs that are set to 1 is odd. This is a parity detector.
