SevIQ

Learning path

Move from circuit laws to live instrumentation.

The SevIQ learning lane is an ordered core path — electronics, then phasors, then radar math — with control theory as an optional side branch you can take whenever feedback shows up. Each stop points at a full chapter, a few practice prompts, and the next practical surface to try.

Learn path map Three core stops in order: electronics, phasors, radar math. Control theory branches off the spine as an optional side branch. 1 2 3 Electronics Phasors Radar math Control theory · side branch

Step 1 · Core path

Stable

Electronics fundamentals

KVL, KCL, Ohm's Law, power, and simple control wiring.

Start module

Step 2 · Core path

Stable

Phasors and complex power

Steady-state sine waves, RMS, impedance, power factor, and three-phase geometry.

Open module

Step 3 · Core path

Stable

Radar math

Echo time, trilateration, bearing, velocity vectors, prediction, and error budget.

Side branch

Take this whenever feedback shows up

Control theory has its own simulator-driven style — target, measurement, output, plant, response metrics, PID states — and stands on its own. It is not a gate between phasors and radar; branch into it when a project needs a loop to hold a setpoint.

Side branch

Stable

Control theory you can test

Feedback loops, step response, on/off hysteresis, PID tuning, disturbances, and practical simulator states — paired with the Control Loop Playground.

How each path page is built

  1. Prerequisites up front, then a link to the full chapter — the path page stays a map, not the explanation.
  2. A few practice prompts and the next practical surface (a tool, lab, or game) to try.
  3. An exit checklist: you know when you are ready to move on.
  4. Calculators stay small and local: Ohm's Law, divider, RMS, power factor, three-phase power, control response, and radar range.
