Logic Gate Quiz9 (Year 9 Exam Prep Task)

What is the basic function of an AND gate?

• To produce a low output when any of the inputs are low

• To produce a high output when any of the inputs are high

• To produce a high output only when all the inputs are high

• To produce a low output only when all the inputs are low

What is the output of an AND gate if both inputs are 1?

• 2

• 0

• 1

• 1

What is the symbol used to represent an OR gate?

• *

• >

• =

• +

What is the output of an OR gate if one input is 0 and the other is 1?

• 3

• 2

• 1

• 0

What is the function of a NOT gate?

• Filters out the input signal

• Inverts the input signal

• Amplifies the input signal

• Delays the input signal

What is the output of a NOT gate if the input is 1?

• 1

• 0

• 2

• 3

What is the truth table for an AND gate?

• 0110

• 1001

• 1100

• 1010

What is the truth table for an OR gate?

• True when the first input is false

• True when all inputs are false

• True when at least one input is true

• True when both inputs are true

What is the truth table for a NOT gate?

• Input (A) | Output (Q) - 1 | 1, 1 | 0

• Input (A) | Output (Q) - 1 | 1, 0 | 0

• Input (A) | Output (Q) - 0 | 0, 1

• The truth table for a NOT gate is: Input (A) | Output (Q) - 0 | 1, 1 | 0

How are logic gates used in digital circuits?

• They are used to perform logical operations such as AND, OR, and NOT.

• They are used to generate random outputs in digital circuits.

• They are used to store data in digital circuits.

• They are used to convert analog signals to digital signals.
