A traffic light is installed at the junction of the railroad and a road. The traffic light is controlled by two switches in the rails placed one mile apart on either side of the junction. A switch is turned on when a train is over it and is turned off otherwise. The traffic light changes from green( logic- 0) to red (logic-1) when the beginning of the train is one mile away from the junction. the light changes back to green when the end of the train is one mile away from the junction. assume that the length of the train is less than 2 miles.
- Obtain a primitive flow table for the circuit.
- show that the flow table can be reduced to four rows
