    Study Notes

    Boolean Logic

    • Boolean logic involves values of TRUE or FALSE, developed by George Boole in the 19th century.

    Boolean Algebra

    • A system for manipulating truth values, important in computing as it aligns with binary representation (0 and 1).

    De Morgan's Law

    • Comprises two key principles for simplification in Boolean algebra:
      • The negation of a conjunction equals the disjunction of the negations: NOT (A AND B) = (NOT A) OR (NOT B).
      • The negation of a disjunction equals the conjunction of the negations: NOT (A OR B) = (NOT A) AND (NOT B).

    Distributive Law

    • Allows multiplication or factoring of expressions within Boolean algebra.

    Associative Law

    • Permits removal of brackets and regrouping variables in Boolean expressions.

    Commutative Law

    • States that the order of terms does not affect the result: A AND B = B AND A.

    Double Negation

    • A fundamental rule stating that negating a variable twice returns the original value: NOT (NOT A) = A.

    Logic Gate Diagram

    • A visual representation of Boolean logic using symbols to denote various logic gates like AND, OR, and NOT.

    Truth Table

    • A systematic method to define output for logic gates based on all input combinations.

    Example Simplification Techniques

    • Simplification of expressions using laws like Identity Law, Redundancy Law, and Commutative Law.
    • For instance, reducing (A.B) + A to simply A by factoring out the common term.

    AND Gate Truth Table

    • A truth table that describes the output of an AND gate based on its inputs.

    OR Gate Truth Table

    • Outlines the outputs of an OR gate for various input combinations.

    XOR Gate Truth Table

    • Describes the exclusive OR operation, detailing when the output is true.

    NOT Gate Truth Table

    • Demonstrates how a NOT gate inverts its input, providing true output for false inputs and vice versa.

    NAND Gate Truth Table

    • Represents the output of a NAND gate, which is the negation of an AND gate.

    NOR Gate Truth Table

    • Illustrates the output of a NOR gate, which is the negation of an OR gate.

    Identity Principles

    • A + 0 = A; Adding 0 does not change the value.
    • A + 1 = 1; Adding 1 results in 1.
    • A . 0 = 0; Multiplying by 0 results in 0.
    • A . 1 = A; Multiplying by 1 keeps the original value.

    Relevant Laws

    • A + A = A; Redundant variables do not change the outcome.
    • A . A' = 0; A AND NOT A always results in false.

    Binary Representation Examples

    • The binary equivalent of 184 is 1011 1000.
    • The binary equivalent of 233 is 11101001.
    • The binary equivalent of 111 is 01101111.
