H446_8_Logic Gates Quiz

What is the primary function of a NOT gate in logic circuits?

• It outputs the same value as the input.

• It inverts the input value.

• It adds two input values.

• It multiplies two input values.

Which of the following is a Boolean algebraic expression for a NOT gate?

• Q = A + B

• Q = A * B

• Q = ¬A

• Q = A / B

What are the possible outputs of a NOT gate when the input is 1?

• 0

• 1

• 2

• 3

Which of the following logic gates is NOT mentioned in the textbook?

• NOT

• AND

• OR

• NAND

What is the Boolean expression for an AND gate?

• Q = A ∨ B

• Q = A ⊕ B

• Q = A ∧ B

• Q = ¬A ∨ (B ∧ C)

Which gate's output is true only if both inputs are true?

• OR gate

• XOR gate

• AND gate

• NOT gate

What is the Boolean expression for an OR gate?

• Q = A ∧ B

• Q = A ∨ B

• Q = A ⊕ B

• Q = ¬A ∨ (B ∧ C)

How does the XOR gate differ from the OR gate?

• XOR is true if both inputs are true

• XOR is true if one input is true, but not both

• XOR is always false

• XOR is true if both inputs are false

What is the Boolean expression for the circuit represented in the diagram?

• Q = A ∧ B

• Q = A ⊕ B

• Q = ¬A ∨ (B ∧ C)

• Q = A ∨ B

Write the Boolean expression Q = ¬((A ⊕ B) ∧ C) using AND, OR, NOT, XOR instead of symbols. Draw the corresponding logic circuit.

• Q = (A AND B) OR C

• Q = NOT((A XOR B) AND C)

• Q = (A OR B) AND NOT C

• Q = (A XOR B) OR NOT C
