XORvärava

XORvärava, also known as an exclusive OR gate, is a fundamental digital logic gate. It performs logical disjunction, in which the output is true if and only if an odd number of inputs are true. This means that if both inputs are the same (either both true or both false), the output will be false. If the inputs are different, the output will be true. The symbol for XOR is often represented by a circled plus sign or the word "XOR".

The truth table for a two-input XOR gate is as follows: Input A | Input B | Output 0 | 0 | 0 0 | 1 | 1 1 | 0 | 1 1 | 1 | 0. This behavior makes XOR gates useful in various applications. They are commonly used in arithmetic circuits, such as adders, where they help determine the sum bit without considering the carry. XOR gates are also employed in error detection and correction systems, and in cryptography for encryption and decryption processes. Their unique property of producing a '1' only when inputs differ makes them a versatile component in digital electronics.
