7.2 In a car security system, digital inputs (a) Key which was '1' When the alarm is activated, (b) Door which is '1' when the door is open and (c) Ultrasonic detector which was '1' when there's movement in the car. We used this description to create a truth table for the system, which looked like this Table 1: tate-output table for the car security system FSM K (input) D (input U(input Horn state) 0 0 0 0 0 The system would sound a horn if the system was energized (K-1) while either the door is open D 1) or an ultrasonic intruder detector signalled movement inside the car (U-1). If State A is the unattacked car and the horn is off State B is trouble, there is an intruder and the horn is on and remains on in this state. a. Draw the state diagram that describes the sequential circuit that simulate the parking controller b. Convert the state diagram to DFF hot controller showing all input, outputs, and rest signals
