An automobile is equipped with an alarm system to indicate each of the following conditions: (a) The key is in the ignition, the door is open, and the engine motor is not running; (b) the lights are on when the key is not in the ignition; (c) the seat belt is not fastened when the motor is running; or (d) the door is open and the motor is running. Show the alarm logic circuit when K = 1.
If the key is in the ignition, D=1 if the door is open, L=1 if the lights are one, M=1 if the motor is running, and S=1 if the seat belt is not fastened.
