13.4.1 Understanding logic gates

• What are logic gates used for in digital electronics?

  Basic logical operations
• Understanding truth tables is essential for designing logic circuits.


  True
• What is the difference between the physical components and symbolic representations of logic gates?

  Physical gates use real components
• What output does an OR gate produce if input A is 1 and input B is 0?

  1
• Match the logic gate with its correct function:

  AND ↔️ High output if all inputs are high

  OR ↔️ High output if any input is high

  NOT ↔️ Inverts the input

  NAND ↔️ High output unless all inputs are high

  NOR ↔️ High output only when all inputs are low

  XOR ↔️ High output if exactly one input is high
• Under what condition does a NOR gate produce a high output?

  All inputs are low
• Logic gates follow Boolean algebra principles.

  True
• What is the output of an OR gate if both inputs are 0?

  0
• Logic gates operate based on Boolean algebra principles


  True
• What output does an OR gate produce if one input is high (1)?

  High output (1)
• A NAND gate is equivalent to an AND gate followed by a NOT
• An XOR gate produces a high output (1) if exactly one input is high (1).


  True
• What is the function of a NOT gate in terms of its output?

  Inverts the input
• An OR gate produces a high output (1) if any input is high (1).
• Under what condition does a NAND gate produce a low output (0)?

  Both inputs high
• An XOR gate produces a high output (1) if both inputs are the same.

  False
• When does an AND gate produce a high output (1)?

  Both inputs high
• A NOT gate inverts the input to produce the output.
• A NOR gate produces a high output (1) only if both inputs are low (0).

  True
• Logic gates follow Boolean algebra principles.


  True
• The AND gate produces a high output (1) if all inputs are high
• What principles do logic gates follow in their operations?

  Boolean algebra
• Match the logic gate type with its symbol:

  AND ↔️ ∧

  OR ↔️ ∨

  NOT ↔️ ¬
• Order the following logic gates based on their common usage: AND, OR, NOT, NAND, NOR, XOR

  1️⃣ AND

  2️⃣ OR

  3️⃣ NOT

  4️⃣ NAND

  5️⃣ NOR

  6️⃣ XOR
• De Morgan's Theorems are used to simplify logic expressions
• The AND gate produces a high output only if all inputs are high
• What is the function of a NOT gate?

  Inverts the input
• The NAND gate is an AND gate followed by a NOT
• What is the output of an XOR gate if both inputs are 1?

  0
• An AND gate produces a high output only if all inputs are high
• What are logic gates used for in digital electronics?

  Performing basic logical operations
• An AND gate produces a high output (1) only if all inputs are high (1).all
• A NOT gate inverts the input signal.

  True
• Under what condition does a NOR gate produce a high output (1)?

  Both inputs are low (0)
• The output of an AND gate is high (1) only if both inputs are high (1)
• What is the output of an AND gate if both inputs are high (1)?

  1
• The output of a NOT gate is the inverse of its input.


  True
• A NOR gate produces a high output (1) only when both inputs are low.
• Match each gate type with its symbol:

  AND ↔️ ∧

  OR ↔️ ∨

  NOT ↔️ ¬

  NAND ↔️ ∧ with overline

  NOR ↔️ ∨ with overline

  XOR ↔️ ⊕
• An OR gate produces a high output (1) if any input is high (1).
