1. Cars nowadays have all sorts of warning systems which produce an alarm when there is any

undesirable situation like door not closed, seat belt not tied, and lights on while the car is turned off.

You are tasked by the automobile manufacturer to design a logic circuit to achieve some of

the functionality. They want you to use the information from three sensors, i.e. door on the

driver's seat (open or close), the ignition (on or off), and the highlights (on or off) to activate

audible alarms in the following scenarios.

(a) The headlights are on while the ignition is off.

(b) The door is open while the ignition is on.

(c) The headlights are on while the door is open.
