False triggering of a Schmitt trigger caused by noise is prevented by
A) high voltage gain.
B) hysteresis.
C) a bypass capacitor.
D) negative feedback.

Question

Quizplus · Accepted Answer

Hysteresis is the key feature of a Schmitt trigger. It results in a range of input voltage levels within which the output voltage remains constant. This means that even when there is noise present in the input signal that causes it to fluctuate around the trigger threshold, the output will not be triggered unless the input crosses a certain hysteresis range. This ensures that the Schmitt trigger is not falsely triggered by noise.
