I'm not sure if I'm proceeding well with this exercise:
Design a synchronous sequential machine with external synchronization which states are coded on \(4\) bits \(q_3 q_2 q_1 q_0\) whose table is the following:
\(
\begin{tabular}{|c|c|c|c|c|c|c|c|}
\hline
q_3 & q_2 & q_1 & q_0 & q_3' & q_2' & q_1' & q_0' \\
\hline
\hline
0 & 0 & 0 & 0 & 0 & 0 & 0 & 1 \\
\hline
0 & 0 & 0 & 1 & 0 & 0 & 1 & 0 \\
\hline
0 & 0 & 1 & 0 & 0 & 1 & 0 & 0 \\
\hline
0 & 0 & 1 & 1 & - & - & - & - \\
\hline
\hline
0 & 1 & 0 & 0 & 0 & 1 & 0 & 1 \\
\hline
0 & 1 & 0 & 1 & 0 & 1 & 1 & 0 \\
\hline
0 & 1 & 1 & 0 & 1 & 0 & 0 & 0 \\
\hline
0 & 1 & 1 & 1 & - & - & - & - \\
\hline
\hline
1 & 0 & 0 & 0 & 1 & 0 & 0 & 1 \\
\hline
1 & 0 & 0 & 1 & 1 & 0 & 1 & 0 \\
\hline
1 & 0 & 1 & 0 & 1 & 1 & 0 & 0 \\
\hline
1 & 0 & 1 & 1 & - & - & - & - \\
\hline
\hline
1 & 1 & 0 & 0 & 1 & 1 & 0 & 1 \\
\hline
1 & 1 & 0 & 1 & 1 & 1 & 1 & 0 \\
\hline
1 & 1 & 1 & 0 & 0 & 0 & 0 & 0 \\
\hline
1 & 1 & 1 & 1 & - & - & - & - \\
\hline
\end{tabular}

a) Draw the correspondent state diagram.
b) Design the machine using Flip-Flop D.
What I'm not sure of is the point "a". Is the diagram I've done correct? Or I missed something?
