$4.(2$ pts$)$ Consider the given network. Is this a Mealy machine or Moore machine?

a$)$ Construct a next state table and state graph. The state graph and state table should use the abstract state definitions where $\backslash (\backslash$mathrm$\{$S$\}0=00,\backslash$mathrm$\{$~S$\}1=01,\backslash$mathrm$\{$~S$\}2=11\backslash ),$ and $\backslash (\backslash$mathrm$\{$S$\}3=10\backslash )$

b$)$ Complete the timing diagram below for the input sequence $\backslash ($ X$=01100\backslash ).$ Indicate any false outputs and specify the correct output sequence.

Assume that:

$-$ X changes midway between the clock pulses

$-$ Initially Q$1=$ Q$2=0$
