Study Notes
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).
