However, by following a transparent-high latch with a transparent-low or opaque-high latch, a master—slave flip-flop is implemented. The resulting circuit is call T flip-flop, which always complements its previous output toggle. The design and application of a "flip-flap-flop" using tunnel diodes Master's thesis. Mathematical Systems Theory I:
I got the required output, which was to make the traffic lights go in the following order: The next task seemed to be very simple too. Again, seems simple enough. I built the circuit on Proteus, and the circuit worked fine. It done exactly as I had asked. I then built it on breadboard, and it didn't work correctly. The lights went in the wrong order. So why would they be acting differently when put into the full circuit?
I have been trying to figure it out for the best part of an hour now and no idea! The task is really to design a state machine to implement the different states of the traffic lights and move between them in the correct sequence.
For a state machine the flip flops should be all be clocked by the same signal, and the flip flop inputs set up so that the system moves from the current state to the next state when the clock edge arrives. You then rather missed the point of using J-K flip flops instead of D-types by just trying to convert them into D-types using an inverter.
J-K flip flops give you a lot more ability to control the output, and I'm guessing the point of the exercise is to get you to fully understand that and learn how to use them.
