Design Racing System

Three turtles are racing against each other. A motion detector is responsible to send a pulse through a wire when each one of them reaches the finish line. At the end of each track, there is a LED light. Design a synchronous system that lights only the LED at the winner track.

You have a clock signal (CLK) which can be used as an input to your system and you can assume its pulse width is half of the pulse width which is generated by the motion detector.

Answer

Notice that when 2nd and 3rd place will reach to the finish line the motion detector will send a pulse for their track as well. Hence, we have to consider this when designing the system.
