Not videos. Not slides. Every module is a working interactive reference built from real engineering practice — concepts, diagrams, and applied problems you actually use.

You have been designing circuits. You have not been designing for the real world. The threat landscape, why standards exist, why functionally-correct boards still fail.
The vocabulary that makes everything else possible. Sources, victims, coupling, near vs far field, dB and dBµV, the spectrum we actually live in.
Every EMI problem starts somewhere. dI/dt, dV/dt, switching edges, current loops, voltage transitions — the physics of noise generation.
Knowledge without a process is just better guessing. The decision framework — source, path, victim — that makes everything actionable.
The schematic has not opened yet — and you are already making EMC decisions. Partitioning, isolation boundaries, port classification, enclosure assumptions.
Every component choice is an EMC decision. Decoupling networks, filter selection, common-mode strategy, ferrites, TVS, transformer choices.
Before routing a single trace — lock the stackup. Reference planes, dielectric heights, plane assignment, why return current shapes everything.
Architecture decided. Schematic done. Stackup locked. Now every decision becomes geometry — placement, partitioning, vias, splits, length matching.
"Connect everything to ground." This instruction has caused more EMC failures than any other. Single-point, multi-point, hybrid, isolated — and when each is wrong.
Filtering and shielding defend the margin. Filter topology, ferrite selection, gasket strategy, slot antennas, why shields fail when grounded badly.
The switching supply is not just a noise source — it is a predictable one. Buck, boost, flyback spectrum signatures. Snubbers. Spread-spectrum modulation.
The PCB is clean. The cable just became a metre-long antenna. Common-mode chokes, pigtail effects, shield termination, connector selection.
Same hardware. Different firmware. Different emission spectrum. Clock dithering, output rate control, sleep states, GPIO toggle patterns.
The board is on the bench. The chamber is two weeks away. Near-field probing, current probes, LISN, building a credible bench measurement.
You are at the compliance chamber. The clock is running at ₹15,000 per hour. Test flow, what fails, what to bring, how to budget your slot.
Every failure has a reason. Every reason has a traceable cause. Real case studies: harmonic hunts, ESD upsets, immunity failures, the fix and the lesson.
Work four real compliance failures from symptom to root cause, then answer scenario questions with the reasoning revealed after every answer. Learn by doing, not watching.
CISPR, FCC, IEC 61000, ISO 7637, MIL-STD-461. You learn to read any standard as a design input, not as a checklist to clear before shipping.
Four products that passed every bench test and failed in the field. None was a wrong component value — each was a gap in the mental model.
