• OR

• AND

• NOT

• XOR

Which logic gate symbol looks like a triangle with a circle at the end?

• AND

• OR

• NOT

• NAND

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

• 1

• 0

• Depends on conditions

• Cannot be determined

For the scenario: “Lights turn on if button is pressed OR voice command is given”, which logic gate is appropriate?

• AND

• NOT

• OR

• XOR

What is the logic expression for the following scenario:

“Lights turn on if the button is pressed OR a voice command is given”

• L = Light turns on

• B = Button is pressed

• V = Voice command is given

• L = B AND V

• L = B OR V

• B = V OR L

• V = L AND B

In the scenario: “Wheelchair moves if seatbelt is fastened AND joystick pushed forward”, which gate is used?

• OR

• NAND

• AND

• NOR

What is the logic expression for the following scenario:

“Wheelchair moves if seatbelt is fastened and joystick pushed forward”

• M = Wheelchair moves

• S = Seatbelt is fastened

• J = Joystick is pushed forward

• M = S AND J

• S = J NOT M

• M = S OR J

• M = S OR J
