An XOR (Exclusive OR) gate is a digital logic gate that outputs a high signal (
) only when its two inputs are different. If the inputs are the same, the output is low ( Core Truth Table
The easiest way to understand an XOR gate is through its behavior: 0 1 1 0 Key Concept
Inequality detector: It asks, “Are these two inputs different?” Strict choice: It means “one or the other, but not both.” Mathematical Symbols Boolean Expression: Algebraic Formula: Practical Applications
Binary Addition: It forms the foundation of half-adders and full-adders in computer CPUs.
Parity Checking: It detects errors in data transmission by checking if the number of 1s is even or odd.
Encryption: Simple XOR operations are used in cryptography because ciphering and deciphering use the exact same key logic.
