please explain to me how to find the values of A(t+1) and B(t+1)

2- Design a 2-bit count-down counter with two JK flip-flops A and B and one input When x = 0, the state of the flip-flops does not change. When x = 1, the state sequence is 11, 10, 01, 00, and back to 11 a. Draw a state diagram for the counter b. Complete the following excitation table. Flip-flop KA Present state input Next state A(t) B(t) JB KB
