Click For Summary
The discussion revolves around creating a state diagram for a circuit with three connected D flip-flops, correcting an initial misunderstanding about the number of flip-flops involved. Participants clarify that with three flip-flops, there are eight possible states (from [000] to [111]), and the state of the system is determined by the collective state of these flip-flops. The importance of the clock pulse (CP) is emphasized, as state changes occur only on the rising edge of the clock signal. Participants also discuss the inputs to each flip-flop based on their current states, leading to a better understanding of state transitions. Ultimately, the conversation concludes with the realization that the clock is a special input not typically shown in state diagrams, and the necessity of eliminating unnecessary stay-in-state paths for clarity.

Thank you very very much for your help and guidance, if it wasn't for you I would have given up long ago.
