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 D flip-flops. 000 001 010 011 (R) (R) (R) (Y) 111 011 101 100 (Y) (G) (G) (G) (Note: Don't leave any cell without selecting either 1 or 0 in the truth table and K map.)
