    Logic gates are fundamental components in digital electronics, performing basic logical functions that are essential for building complex circuits. Each logic gate has a unique symbol that represents its function in circuit diagrams.

    Types of Logic Gates and Their Symbols

    1. AND Gate: Symbol: A \ &--- Q / B Function: Produces a high output (1) only if all inputs are high (1). Truth Table: A | B | Q ----------- 0 | 0 | 0 0 | 1 | 0 1 | 0 | 0 1 | 1 | 1

    2. OR Gate: Symbol: A \ ≥--- Q / B Function: Produces a high output (1) if at least one input is high (1). Truth Table: A | B | Q ----------- 0 | 0 | 0 0 | 1 | 1 1 | 0 | 1 1 | 1 | 1

    3. NOT Gate: Symbol: A ---|>o--- Q Function: Inverts the input; produces a high output (1) if the input is low (0) and vice versa. Truth Table: A | Q ----- 0 | 1 1 | 0

    4. NAND Gate: Symbol: A \ &o--- Q / B Function: Produces a low output (0) only if all inputs are high (1). Truth Table: A | B | Q ----------- 0 | 0 | 1 0 | 1 | 1 1 | 0 | 1 1 | 1 | 0

    5. NOR Gate: Symbol: A \ ≥o--- Q / B Function: Produces a low output (0) if at least one input is high (1). Truth Table: A | B | Q ----------- 0 | 0 | 1 0 | 1 | 0 1 | 0 | 0 1 | 1 | 0

    6. XOR Gate: Symbol: A \ =1--- Q / B Function: Produces a high output (1) if the inputs are different. Truth Table: A | B | Q ----------- 0 | 0 | 0 0 | 1 | 1 1 | 0 | 1 1 | 1 | 0

    7. XNOR Gate: Symbol: A \ =o--- Q / B Function: Produces a high output (1) if the inputs are the same. Truth Table: A | B | Q ----------- 0 | 0 | 1 0 | 1 | 0 1 | 0 | 0 1 | 1 | 1
