Class-D Amp for a phase-locked loop
Simulate a phase-locked loop live in your browser. This runs the real Class-D Amp solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.

Presets
To capture a signal faithfully you must sample above twice its highest frequency — the Nyquist rate. Sample too slowly and a high frequency masquerades as a lower one: aliasing. Push the signal frequency above half the sample rate and watch the reconstructed wave collapse to a false, slower tone.

Presets
Passive filters shape a signal's frequency content with resistors, capacitors, and inductors. An RC low-pass or high-pass has a cutoff at 1/(2πRC) where the response drops 3 dB; an RLC bandpass resonates at 1/(2π√(LC)) with sharpness set by its quality factor Q.

About this simulation
The full Class-D Amp tool models a phase-locked loop with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.

Frequently asked questions
- How do I simulate a phase-locked loop?
- Open this page and use the live Class-D Amp tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.
- Is it free?
- Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.
- Can I use my own numbers?
- Absolutely — every input is adjustable, and with data import you can drive a phase-locked loop from your own measurements.
