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
