What is the operational function sign for the XOR gate?

The operational function sign for the XOR gate is indeed XOR, which stands for "exclusive or." This gate operates based on a unique principle where it produces a true (or high) output only when the number of true inputs is odd. In simpler terms, for two binary inputs, the XOR gate outputs true only if one input is true and the other is false. This characteristic distinguishes it from other gates like AND, OR, and NAND.

Understanding the XOR gate's function is crucial in digital circuits and logical operations, as it is often used in applications where a binary decision needs to be made based on distinct input conditions. Its ability to signal whether exactly one (and not both) of the inputs is true makes it an essential component in various logic circuits and computational functions.
