    Boolean Algebra

    Boolean Algebra is a mathematical system for dealing with logical operations and is the foundation of digital electronics. It is a way of representing logical operations using algebraic expressions.

    Boolean Operators

    • NOT (Inverter): Negates the input, represented by ¬ or '
      • Example: ¬A (NOT A)
    • AND (Conjunction): Produces an output of 1 only if all inputs are 1, represented by ∧
      • Example: A ∧ B (A AND B)
    • OR (Disjunction): Produces an output of 1 if at least one input is 1, represented by ∨
      • Example: A ∨ B (A OR B)
    • XOR (Exclusive OR): Produces an output of 1 if exactly one input is 1, represented by ⊕
      • Example: A ⊕ B (A XOR B)

    Boolean Laws

    • Commutative Law: The order of inputs does not affect the output
      • Example: A ∧ B = B ∧ A
    • Associative Law: The order in which operations are performed does not affect the output
      • Example: (A ∧ B) ∧ C = A ∧ (B ∧ C)
    • Distributive Law: The AND operation distributes over the OR operation
      • Example: A ∧ (B ∨ C) = (A ∧ B) ∨ (A ∧ C)

    Boolean Expressions

    • A Boolean expression is a combination of variables, constants, and Boolean operators
    • Can be simplified using Boolean laws and theorems
    • Can be implemented using logic gates in digital circuits

    Boolean Laws

    Commutative Law

    • The order of inputs does not affect the output.
    • Example: A ∧ B = B ∧ A.

    Associative Law

    • The order in which operations are performed does not affect the output.
    • Example: (A ∧ B) ∧ C = A ∧ (B ∧ C).

    Distributive Law

    • The AND operation distributes over the OR operation.
    • Example: A ∧ (B ∨ C) = (A ∧ B) ∨ (A ∧ C).

    Boolean Expressions

    • A Boolean expression is a combination of variables, constants, and Boolean operators.
    • Boolean expressions can be simplified using Boolean laws and theorems.
    • Boolean expressions can be implemented using logic gates in digital circuits.
