Learn about the applications of the Schmitt trigger, and advantages as a comparator. That is, it provides feedback which is not reversed in phase, but in this case the signal that is being fed back is a negative signal and keeps the output driven to the negative supply voltage until the input drops below the lower design threshold. Many (most?) With only one input threshold, a noisy input signal near that threshold could cause the output to switch rapidly back and forth from noise alone. Schmitt trigger circuit is an active circuit. We know that capacitance opposes a change in voltage.
