2. (20 points) Instead of using a Moore machine to implement the sequence detector in problem 1, derive a state diagram for a Mealy machine that will perform this operation. 1. (20 points) For this problem, we want to design a circuit that checks for the input sequence 00101. Your circuit will have a one-bit input W and a one-bit output Z where Z-1 if the last five values of W observed on each positive edge of the clock are...
