Op-amp circuit / Schmitt trigger circuit with reference voltage

This simulation demonstrates the working of an inverting Schmitt Trigger using an operational amplifier with a noisy sinusoidal input signal. The top part shows the waveform analysis where the orange waveform represents the noisy input signal, and the green waveform represents the clean, squared output signal. Despite the noise in the input, the Schmitt Trigger effectively converts the signal into a stable square wave by applying hysteresis — switching between high and low output states only whe

This simulation shows the operation of a Schmitt Trigger using an op-amp with positive feedback. The orange waveform represents a noisy sine wave input signal, while the green waveform shows the clean digital output. As the input rises and crosses the upper threshold voltage, the output instantly switches to 5V. When the input drops below the lower threshold, the output flips to -5V. This hysteresis behavior ensures that small fluctuations or noise in the input do not cause unwanted switching. T
