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.

Question

An LM flip-flop works as follows:

If LM = 00, the next state of the flip-flop is 0.

If LM = 01, the next state of the flip-flop is the same as the present state.
If LM = 10, the next state of the flip-flop is the complement of the present state.
If LM = 11, the next state of the flip-flop is 1.
(a) For the sequential circuit shown in Figure 8, write the next-state equations for
the flip-flops.
