Free Boolean Logic Gate & Truth Table Generator

Digital electronics and computer architecture rely on fundamental Boolean logic gates to process binary signals (0 and 1). Truth tables detail every possible binary input combination and corresponding output state. Our free logic gate calculator enables computer science and digital design students to use a truth table generator online, evaluate boolean logic gate solver circuits, and analyze xor gate truth table calculator outputs.

Mathematical Formulas & Calculation Methods

Boolean Logic Expressions

Standard Boolean algebraic expressions for 2-input gates.

AND: Y = A·B | OR: Y = A+B | NAND: Y = (A·B)' | NOR: Y = (A+B)' | XOR: Y = A⊕B | XNOR: Y = (A⊕B)'

Worked Step-by-Step Examples

Example 1: XOR Gate with Inputs A = 1 (HIGH) and B = 0 (LOW)

"Evaluate output Y and review XOR truth table."

Steps:

  • XOR gate output is 1 when inputs differ (A ≠ B).
  • Inputs (1, 0) differ → Output Y = 1 (HIGH).
  • Truth Table: (0,0)->0, (0,1)->1, (1,0)->1, (1,1)->0.
Result: Output Y = 1 (HIGH).

What is Boolean Logic Gate & Truth Table Generator?

A logic gate calculator evaluates 2-input binary logic circuits and generates standard truth tables.

A NAND or NOR gate is called a 'universal gate' because any Boolean logic circuit can be built exclusively using NAND or NOR gates.

How to Use Boolean Logic Gate & Truth Table Generator

  1. 1Select logic gate type (AND, OR, NAND, NOR, XOR, XNOR).
  2. 2Set Input A and Input B binary signals (0 or 1).
  3. 3View instant Output Y signal (0/LOW or 1/HIGH), Boolean expression, and full 4-row truth table.

Key Features

  • Supports 6 core logic gates: AND, OR, NAND, NOR, XOR, XNOR.
  • Generates complete 4-row binary truth table matrix.
  • Displays formal Boolean algebraic equation.

Frequently Asked Questions

What is the difference between OR and XOR?

An OR gate outputs 1 if either OR both inputs are 1; an XOR (Exclusive OR) gate outputs 1 ONLY if exactly one input is 1 (not both).
