For there to be an EMI problem
There have to be 3 things:
1. A noise generator
2. A susceptible receiver
3. And a coupling mechanism
– Coupling mechanisms are usually parasitic components or paths
And there are 3 coupling mechanisms (the 3 stooges):
1. Capacitive
2. Inductive
3. Common Impedance (not “resistive,” we’ll see why later)
