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

This Simulation shows a Schmitt Trigger circuit using an op-amp, which converts a noisy sine wave (orange) into a clean square wave (green). The Schmitt Trigger operates with hysteresis, meaning it switches its output at different threshold voltages depending on the input's direction. This effectively removes noise and ripple, ensuring sharp transitions. As seen in the oscilloscope output, the noisy analog signal is cleaned up into a crisp digital output, making the @circuit ideal for signal con
