Understanding the use of logic gates

• What are the three basic logic gates in Boolean Logic?

  AND, OR, NOT
• The NOT gate inverts the input, changing 0 to 1 and 1 to 0.


  True
• Why are basic logic gates considered the building blocks of digital circuits?

  Perform logical operations
• Boolean Logic deals with binary values, typically represented as 0 and 1.
• What are logic gates used to create in digital circuits?

  Decision-making processes
• An AND gate outputs 1 only if both its inputs are 1.
• What is the output of an AND gate when both inputs are 0?

  0
• The AND gate outputs 0 if any of its inputs are 0.


  True
• The AND gate outputs a 1 only if all of its inputs are 1
• The OR gate outputs a 1 if any of its inputs are 1
• What is a logic gate used for in digital circuits?

  Produces a single binary output
• An AND gate with two inputs outputs 1 only if both inputs are 1


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

  0
• The NOT gate inverts the input signal


  True
• Combinational circuits combine multiple logic gates to perform specific logical operations
• What type of input does a NOT gate take?

  Binary input
• If the input to a NOT gate is 0, the output is 1.


  True
• Why are NOT gates essential in digital systems?

  To negate signals
• Combinational circuits have memory or feedback loops.

  False
• An AND gate followed by a NOT gate creates a NAND gate.
• Under what condition does an AND gate produce an output of 1?

  All inputs are 1
• A NOT gate inverts the input, changing 0 to 1 and 1 to 0.


  True
• The circuit for the logical expression (A AND B) OR C uses an AND gate and an OR gate connected in series.
• Boolean Logic deals with binary values, typically represented as 0 and 1.
• Match the Boolean logic gate with its definition:

  AND ↔️ Output is 1 only if all inputs are 1

  OR ↔️ Output is 1 if any input is 1

  NOT ↔️ Inverts the input
• Order the key Boolean logic operations by their output conditions:

  1️⃣ AND: Output is 1 only if all inputs are 1

  2️⃣ OR: Output is 1 if any input is 1

  3️⃣ NOT: Inverts the input
• The AND operation outputs 1 only if all inputs are 1.


  True
• Match the logic gate with its symbol:

  AND ↔️ AND

  OR ↔️ OR

  NOT ↔️ NOT
• An AND gate followed by a NOT gate creates a NAND gate.


  True
• The AND gate outputs 1 only if both inputs are 1.
• What is an AND gate used for in Boolean Logic?

  Produces a single binary output
• Boolean Logic deals with binary values represented as 0 and 1


  True
• The NOT gate changes 0 to 1 and 1 to 0


  True
• A NAND gate is a combination of an AND gate followed by a NOT gate.
• The OR gate outputs a 1 if any of its inputs is 1
• What is the output of a NOT gate if the input is 1?

  0
• The NOT gate is a fundamental logic gate in Boolean Logic.
• The NOT gate produces an output that is the inverse of the input.
• If the input to a NOT gate is 1, the output is 0.


  True
• Combinational circuits combine multiple logic gates, such as AND, OR, and NOT gates.
