Gate theory
An XOR gate, or exclusive OR gate, produces a high output when its inputs are different.

Understand XOR gate logic through live input-output behavior
XOR logic is useful for difference detection: matching inputs produce 0, while different inputs produce 1. The simulator helps students connect symbols, Boolean expressions, truth tables, and circuit output without needing physical hardware.
Understand XOR truth table behavior.
Compare XOR with OR and XNOR logic.
Recognize XOR in adders and parity circuits.
Use the simulator to test exclusive OR input combinations.
Where this gate is used
- Half adder sum output
- Parity generation and checking
- Difference detection
- Digital circuit design practice
How the interactive lab works
Open the XOR gate lab, toggle the binary input controls, and watch the output update immediately. The visual circuit and truth table make each Boolean result easier to verify.
XOR Gate FAQs
What is an XOR gate?
