The goal of this project is to designthe automation for a condominium complex securitysystem. The project is now in the prototype stage, where asimplified version of the security system will be built. Your taskis to design this simplified security system.
The security system to be designed hasto be very simple. The minimum requirement is that it should have afront gate sensor and a motion detector sensor. If activated, thefront gate security system should play the front gate melody.Similarly, the motion detector component of the security system, ifactivated, should play the motion detection melody. Inprinciple, the security system should operate in the following way.It is assumed that the system is initially in a reset state. Thesecurity system requires two consecutive input warning signalsbefore the motion detection melody or the front-gate melody isplayed. The two input signals are the front gate alarm (FGA)and the motion detection alarm (MDA). The encoding of the inputsignals is as follows:
FGA
MDA
Meaning
0
0
No alarm
0
1
Motion detectionalarm activated
1
0
Front gate alarmactivated
1
1
Both alarms areactive
The condominium complex has areceptionist and a security guard on duty. Either of them can callthe police immediately if alarmed. The outputs of this securitysystem are: no melody (00), motion detection melody (01) and frontgate melody (10). Note: Any unused state encoding in your designshould have the initial state as the next state.
1. Create a state definition table here that describes in plainEnglish what each state in your machine means and what binaryvalues you have assigned to represent each state, inputs, andoutputs.
2. Show your state diagrams, state transition tables and yourcircuit planning work (Karnaugh maps/equations) used in your designprocess. (You can do this by hand if you wish, donot show the full circuit schematic here.)
3. List your final design equations and required logicgates (including types of Flip-Flops) needed to complete thiscircuit.
