I understand that a Schmitt trigger is used to convert any waveform into a square wave, but I'm struggling to grasp how it actually works. Could someone explain its working principle in simple terms?

A Schmitt Trigger turns any noisy or irregular signal into a clean square wave by using two voltage thresholds:
- Rising Signal: When the input goes above the upper threshold, the output switches to HIGH.
- Falling Signal: When the input drops below the lower threshold, the output switches to LOW.
- Hysteresis: The gap between the two thresholds prevents the output from flipping back and forth due to small changes or noise.
It uses positive feedback to ensure smooth and stable transitions. Think of it as a circuit that "cleans up" signals for reliable digital processing.
