Sensor Signal Chain
Amp, ADC, noise. This multi-solver chains 3 solvers into a single guided workflow — run each step in order and carry the result forward.

The op-amp is the fundamental building block of analog electronics. With negative feedback, its gain is set entirely by external resistors: an inverting amp gives −R2/R1, a non-inverting amp 1+R2/R1. An integrator uses a feedback capacitor to output the running integral of its input.

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.

Build a signal from a few sine tones plus noise, and the discrete Fourier transform recovers exactly which frequencies are present — the foundation of all signal processing.

Frequently asked questions
- What is the Sensor Signal Chain multi-solver?
- Sensor Signal Chain is a guided workflow that chains 3 individual PolySim solvers into one end-to-end analysis, piping each result into the next step.
- Is it free to use?
- Yes. Every step runs entirely in your browser using real numerics — no install, no account, no cloud cost. Custom or private solver packs are available as a paid service.
