Exercise 5.17: Flag Monitor
Develop an FSM for a circuit that monitors a l ag such that, if the l ag remains constant
within a given time window, the output copies the measured (constant) l ag value.
This is illustrated in i gure 5.24; if l ag_in has no transitions at all while window is high,
then l ag_out gets the value of l ag_in ; otherwise, it keeps the same value that it had
when the time window started.
