I need help please to design a sequential circuit has two D flip-flops A and B, two inputs E and X. If E=0, the circuit remains in the same state regardless of the value of the x. When E=1 and x=1, the circuit goes through the state transitions from 00 to 01 to 10 to 11 back to 00, and repeats. When E=1 and x=0, the circuit goes through the state transitions from 00 to 11 to 10 to 01 back to 00, and repeats. Draw the state diagram and find out the state equation

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.
