Presets

The Nyquist–Shannon theorem says you must sample faster than twice the highest frequency. Sample too slowly and a high frequency masquerades as a low one — aliasing — which is why anti-alias filters guard every ADC. Educational tool.

Governing equation

Reading this result: Undersampled: fs=8 Hz is below the 10 Hz Nyquist rate, so the 5 Hz tone masquerades as a false 3.0 Hz signal.

About this simulation

The full Sampling & Nyquist tool models a capacitor bank 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 capacitor bank?
Open this page and use the live Sampling & Nyquist 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 capacitor bank from your own measurements.
