Design a digital security system for a four-door sedan car. There are sensors on all doors, hood, gas cover, and the trunk. When the car is locked, an alarm will sound if somebody tries to force open the door, hood, gas cover, the trunk, or tries to push/move the car. When the car is unlocked, the user is allowed to open the doors, hood, gas cover, or the trunk and drive the car. A shock sensor detects any major vibrations or move. Shock sensor sends out ‘0' when a shock/vibration is sensed. All other sensors send out ‘1' when it is in the closed condition. That is, when the door is closed, the door sensor sends out ‘1' to the security system. When a ‘1' is sent to the alarm (buzzer), it alarms. The lock sends out a ‘1' when it is locked. Draw a block diagram of the security system. Express the security system as a Function ‘F'. Draw the gate-level circuit for the security system. Explain the process of building the gate-level circuit. Use only and, or, not gates. Clearly state the assumptions made, if any.
