Design a Traffic Light Controller (TLC) digital circuit which will operate in the following sequence: Red, Red, Red Yellow, Green, Green, Green, Yellow, Red, Red, Red, Yellow, Green, Green, Green, and repeat. The time of each state (Green or Red or Yellow) will be decided based on the clock cycle frequency (T=1/f). The sequence is shown in the below state diagram, design the Traffic Light Controller (TLC) using T flip- flops. 000 001 010 011 (R) (R) (R) (Y) 111 110 101 100 (Y) (G) (G) (G) U5 PLD1 구 clk Red Yell F Hz Grn Traffic Light Controller S1 VCC S2 5.0V S3 U4 TRAFFIC_LIGHT_SINGLE
