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

This simulation showcases the operation of a Schmitt Trigger circuit with a noisy sinusoidal input signal. In the waveform display, the orange signal represents the noisy input, while the green square wave is the output. This output is inverted, meaning when the input crosses the upper threshold, the output switches low, and when it drops below the lower threshold, the output switches high. This behavior is due to the inverting configuration of the op-amp-based Schmitt Trigger, as shown in the c
