A = Movement Sensor (Produces a 1 if movement is detected)
B = Sound Sensor (Produces a 1 if sound is detected)
C = Light Sensor (Produces a 1 while light is detected)
Y = Alarm (Produces sound when it receives a 1)
This circuit should mean that if the lights are off and either sound or movement or both are
detected, the alarm will sound.
(a) Write a Boolean expression based on the scenario given.
(b) draw logic circuit based on Boolean expression
