38. Schmitt Trigger
•switching threshold on a positive-going input is a higher
voltage level than switching on the negative-going signal
•a bistable circuit in which the output increases to a steady
maximum when the input rises above a certain threshold,
and decreases almost to zero when the input voltage falls
below another threshold.
