Question

For a car ignition to be turned on: (i) the driver must be in the car having all the doors locked having the gear in parking or neutral state, or (ii) the car can be put on using a remote starter from outside without the driver in the car, but all the car doors must be locked with hand brake on and gear in parking state or neutral. Any deviations from these two conditions will set the car security alarm on. i. What are the variables to be used in representing the states? ii. Design a logic circuit for the scenario iii. Modify the design to set the car alarm on for a second after the ignition must have been on for five minutes provided the doors, gear and handbrake are at the initial state and then off the ignition if the states remain the same after the last second.
