Sensor Signal Chain for a three-phase motor
Built for engineers using it for real design work. Go from concept to a running model in the browser, then scale to the cloud when needed. Simulate a three-phase motor live below — adjust the inputs and watch it respond, right in your browser.

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.
