Problem 4: (20 points)
 Design a Moore sequential circuit with input X and output Z that meets the following requirement.
Z= 1, ifthere are at least two I's appearing in the last three inputs, and Z= 0, otherwise.
 Example
 x=001101100101000...
Z=000111110001000...

(b) (10%) Implement the circuit with three D flip-lops and one majority gate MAJ.
