A schmitt trigger is a logic input type that has hysteresis on the input voltage threshold levels. it is available in many logic families. basically it uses some internal positive feedback to raise the threshold when the input is low and to lower the threshold when the input is high. a schmitt trigger is a decision-making circuit. it is used to convert a slowly varying analogue signal voltage into one of two possible binary states, depending on whether the analogue voltage is above or below a preset threshold value. a comparator can do much the same job.
