A three way intersection is in need of a traffic signal control system and you have been assigned thetask to design and implement the system. Each direction has only one lane and one set of signalcontrol lights (green, yellow and red). Your design should only allow one go or green light at atime. Further, all transitions from green to red should go through an intermediate 2-4 secondsyellow light. and draw the design of the schematic

Also, express the signum function in terms of the unit step function.
