Category: Schmitt triggers 

A Schmitt trigger is a type of comparator circuit with built-in hysteresis, meaning it uses two different threshold voltages to determine when its output switches between high and low states. This dual-threshold behavior prevents rapid, noisy, or slowly changing input signals from causing erratic output transitions, making the circuit excellent for cleaning up noisy waveforms, debouncing mechanical switches, and converting analog signals into crisp digital pulses. By ensuring that the input must cross a higher threshold to switch one way and a lower threshold to switch back, a Schmitt trigger provides stable, predictable switching even in electrically noisy environments.
