What is the function of hysteresis in a comparator?
Pick an answer to check it.
Answer: A. To prevent input noise from causing unstable output signals
Hysteresis gives a comparator two slightly different switching thresholds. Small noise on a slow input then cannot make the output chatter back and forth.
Tip: Hysteresis stops noisy chatter.
