 An LM flip-flop works as follows:

If LM = 00, the next state of the flip-flop is 0.
%3|
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.
(b) Using these equations, construct a transition table and draw the state graph.
