This simulation shows a Schmitt Trigger with noisy input, a useful circuit in signal processing for noise immunity and waveform shaping. At the top, we see the input signal (yellow waveform) mixed with noise. Despite the distortions, the output (green square waveform) remains stable and clean due to hysteresis in the Schmitt Trigger. The input is a sinusoidal wave of 1 kHz with added random disturbances. Without a Schmitt Trigger, such noise would cause multiple unwanted switching at the compara
