Understanding Logic Gates

What is the function of an AND gate?

• It outputs 1 only if both inputs are 1.

• It outputs 1 if at least one input is 1.

• It inverts the input signal.

• It outputs 0 only if both inputs are 0.

Which logic gate is also known as an inverter?

• AND gate

• OR gate

• NOT gate

• NAND gate

What is the Boolean expression for an OR gate?

• Q = A AND B

• Q = NOT A

• Q = A OR B

• Q = A XOR B

How many inputs does a typical NOT gate have?

• Two

• One

• Three

• Four

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

• Depends on the circuit

• Undefined

• 1

• 0

Which of the following is a Boolean operator?

• ADD

• SUBTRACT

• AND

• MULTIPLY

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

• Undefined

• 1

• 0

• Depends on the circuit

What is the Boolean expression for a NOT gate?

• Q = A XOR B

• Q = A AND B

• Q = A OR B

• Q = NOT A

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

• 1

• 0

• Depends on the circuit

• Undefined
