Latches and Flip Flop

Just like logic gates, the latches and flip-flops are the important elements of an electronic circuit. The logic gates form the important part of combinatorial circuits, while the latches and flip-flops form the essential part of a sequential circuit. Sequential circuits form the important concept of automata theory in electronics and electrical engineering, these circuits are a kind of logic circuit whose output depends on both present input and past inputs, that is, the input history.

Design a counter which counts down, with the repeated sequence: (2, 1, 0, 2, 1, 0, …) when the input to the counter circuit is 1. The counter doesn’t count (stays at the same state) when the input is 0. The circuit is to be designed by treating the unused states as don’t care conditions. Fill out state transition table, and draw state diagram and your schematic for the design. Use positive edge D flip flops in your design.
