A traffic light system uses logic gates as part of the control system. The system is operated when the output D has the value . This happens when either (a) signal A is red or (b) signal B is green and signals B and C are both red( NOTE: Assume for this problem that red=0 and green =1) Deduce the truth table for the system and the Boolean expression from the truth table, Hence Design a logic circuit or network
