(16 pts) Design a sequential circuit with one D flip flop A, one D flip flop B and one input X. When X - 1, the state of the circuit remains the same. when X = 0, the circuit goes through the state transitions AB-10 to 01 to 11 to 00, back to 10, then repeats. a) Show your state diagram or state table, K-maps, FF input equations, and the logic diagram. b) Repeat for SR flip flops 7
