For the first version, your state machine should simply produce a present output whenever the input is present and greater than 38 degrees. Otherwise, the output should be absent. (b) For the second version, your state machine should have hysteresis. Specifically, it should produce a present output the first time the input is greater than 38 degrees, and subsequently, it should produce a present output anytime the input is greater than 38 degrees but has dropped below 36 degrees since the last time a present output was produced. (c) For the third version, your state machine should implement the same hysteresis as in part (b), but also produce a present output at most once per day.
