Details



A Schmitt Trigger is a comparator circuit with hysteresis. This means that the switching action can occur at different points for a given signal. The Schmitt Trigger retains its output until a large enough signal is received to switch it. This forces switching only on significant voltage changes compared to the rest of the signal. So if you have a noisy signal it will clean the signal in slightly different ways then a traditional comparator.

Here is an example of the Schmitt Trigger handles a slightly noisy signal. U shows the input signal. With A showing a traditional comparator, and B showing a Schmitt Trigger handling the same signal.
