- Basic Concepts
- XOR gate is a widely used logic gate available in IC form
- It outputs 1 when odd number of inputs are high
- Can have infinite inputs and only one output
- Most commonly used with two or three inputs
- Boolean Expressions
- Two-input XOR: Y = A⊕B
- Three-input XOR: Y = A⊕B⊕C
- Implementation Methods
- Can be built using basic logic gates, NAND, NOR, NOT, AND, OR
- Minimum four NAND gates required for two-input implementation
- Minimum five NOR gates needed for three-input implementation
- Can be constructed using more than five NOR gates
- Applications
- Widely used in computer arithmetic section
- Acts as inequality detector when inputs are unequal
