An L-M flip-flop works as follows: If LM = 00, the next state of the flip-flop is 1. 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 0. (a) Complete the following table (use don’t-cares when possible): (b) Using this table and Karnaugh maps, derive and minimize the input equations for a counter composed of three L-M flip-flops which counts in the following sequence: ABC = 000, 100, 101, 111, 011, 001, 000, . . .

An L-M flip-flop works as follows:
If LM = 00, the next state of the flip-flop is 1.
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 0.
(a) Complete the following table (use don’t-cares when possible):
(b) Using this table and Karnaugh maps, derive and minimize the input equations
for a counter composed of three L-M flip-flops which counts in the following
sequence: ABC = 000, 100, 101, 111, 011, 001, 000, . . .
