This simulation is a Square and Triangle Wave Generator using two operational amplifiers. The first op-amp is configured as a comparator with hysteresis (Schmitt trigger) to generate a square wave, while the second op-amp works as an integrator to produce a triangle wave. The square wave output (green) continuously charges and discharges the capacitor through the resistor network, resulting in the triangular waveform (blue). The frequency of oscillation depends on the resistor and capacitor valu

This simulation shows a classic op-amp–based waveform generator that produces both square and triangle wave outputs. The first op-amp is configured as a Schmitt trigger with positive feedback, creating a stable square wave that switches between the supply rails. Its output drives the second op-amp, which is set up as an integrator using R3 and C1. When the square wave is applied to the integrator, it generates a linear rising and falling voltage, forming the triangle wave. The triangle waveform
