The Summing Amplifier shown here demonstrates how multiple harmonic sine waves can be combined to form a square wave using the principle of Fourier synthesis. In this simulation, five harmonics — the fundamental frequency and its odd harmonics (3rd, 5th, 7th, and 9th) — are generated individually and then summed by the op-amp-based summing amplifier. Each harmonic has a specific amplitude ratio and phase relation, such that when added together, the resulting waveform closely approximates a squar

This simulation shows how an op-amp summing amplifier takes multiple input signals and combines them into one clean output. You can see three different waveforms applied at the input side—typically a sine wave, a square wave, and a triangle wave. Each input passes through an equal-value resistor, which is important because it makes every signal contribute the same amount to the final result. Inside the circuit, the inverting input of the op-amp sits at what’s called a virtual ground. Even though

A square wave is not a single signal but a combination of multiple sine waves added together at specific frequencies and amplitudes. This simulation demonstrates that concept using an op-amp based summing amplifier. Five sinusoidal inputs, each representing a harmonic component of a square wave, are applied through equal input resistors. The operational amplifier linearly sums these signals and produces a composite output waveform. The lowest-frequency harmonic defines the overall shape, while h
