i want answer for problem2

Problem 1: a sequential circuit contains two flip flop A and B and and input x. The flip flop works as counter only when x=1. The value of x does not have any effect except in the initial state (00). Derive state table and state diagram. Problem 2: Given the following state table of a synchronous sequential circuit which has two inputs (X,Y) and one output (Z). (a) Is this circuit a Moore or Mealy design? (b) derive the state diagram and logic diagram. Current X Y Next z State State 0 0 0 0 1 0 0 1 0 1 0 1 0 0 1 0 1 1 0 1 0 0 1 0 1 0 1 1 0 1 1 0 1 0 1 1 1 0 1
