This simulation shows a classic op-amp relaxation oscillator that generates both square and triangle waveforms. The left op-amp operates as a Schmitt Trigger, switching between positive and negative saturation based on the feedback network formed by R1 and R2. Its output creates a stable square wave, which then drives the integrator stage on the right. The right op-amp, together with R3 and capacitor C1, integrates the square wave to produce a clean, linear triangle waveform. As the capacitor ch

This simulation demonstrates a Full-Wave Rectifier, a circuit that converts both halves of an AC input signal into pulsating DC. It uses four diodes arranged in a bridge configuration. During the positive half cycle, two diodes conduct, allowing current to flow through the load in one direction. In the negative half cycle, the other two diodes conduct, maintaining current flow in the same direction through the load. As seen in the waveform, the output (green) remains positive throughout, showing
