It's a project of Digital Logic Design. You have to make a traffic signal following the given conditions mentioned and you should use some of the flip flop preferably JK flip flop, make the truth table, excitation table, input equations , expression and then implement the circuit on Proteus that will work with the conditions like the traffic signal and while drawing circuit on proteus use logic gates and flip flop , input and output only.
In this Task you will design a traffic light control system for the intersection of two roads. One of the roads is busy (A) while the other road (B) is quiet. It makes no sense to stop the traffic on the busy road if there are no cars waiting to pass on the quiet road. For this reason, the traffic light control systems incorporates an inductive loop sensor (S) into road B to detect when a vehicle has arrived and is waiting. You often see these sensors as a rectangular cut in the roads just before intersections. The sensor outputs a HIGH pulse when a car passes over it. The traffic light system has two sets of opposing lights, one set for each road as laid out in the figure below. The traffic lights are labelled A (controlling the busy road A) and B (controlling the quiet road B). Each traffic light has three possible outputs: red, orange and green. The sensor in the quiet road B is called S QUIET ROAD BUSY ROAD Figure 1: The traffic light system. A is a busy road while B is a quiet road. All of the traffic lights in road A act simultaneously, as do the traffic lights in road B. The S blocks are vehicle s mors which output a HIGH pulse whenever a vehicle passes over them When traffic light A is green, output Ag is HIGH, when it is orange. Ao is HIGH and when it is red. Ar is HIGH. A similar set of outputs are available for traffic light B When a traffic light changes colour it always follows this sequence: green-orange-red-green It is critical that the traffic lights only change to green AFTER the opposing traffic light is red. There is a "guard time" between these changes. In this system the guard time is 10 seconds (In practice this a function of the speed limit on the road). Likewise the orange light is lit for 10 seconds between the green and red lights. Normally the traffic light allows for traffic to travel on road A. When a car arrives on road B, the B traffic light changes to green (after the A traffic light has turned orange then red) to allow the vehicle through and stays green for 30 seconds. After that time has elapsed, the traffic light A, will once again change to allow cars through on road A. Assume that the system is clocked at 100 mHz (m-milli, M-Mega) which means that there is one clock cycle every 10 seconds. Design the sequential circuit for the control system using: Algorithmic State Machines and Present state Next state diagrams. Minimise the number of memory elements in your system and before you begin identify all the inputs and outputs in your system. Question 1.1 (40 Points) Draw the ASM chart for this system. Remember to include state numbers and labels for your states Question 1.2 (10 Point) Draw the present state next state diagram. Hint: carefully consider all the don't care conditions as it may make the task much simpler than it seems Question 1.3 (15 Points) Find the simplified output Boolean logic equations for the sequential circuit in your system. You may use Karnaugh Maps, Boolean algebra or simple impection to determine them Question 1.4 (20 Points) Find the simplified output Boolean logic equations for the the combination circuit for the outputs of your system. You may use Karnaugh Maps, Boolean algebra or simple inspection to determine thems Question 1.5 (35 Points) Draw your final circuit diagram. Clearly label all inputs and outputs
