"So there’s a thing I call the EMC fire triangle, and that is, the idea that a lot of us learned as kids that to have a fire, you need three things. You need fuel and you need oxygen and you need a heat source. And if you can take away one of those things, you’ve put out the fire. So you can smother it with a blanket and that takes away the oxygen or you can pour water on it that essentially takes away the heat.
To have an EMC problem, you need three things. You need a noisy source, a sensitive victim, and a coupling path between them. And that coupling path can either be radiated or it can be conducted when you’ve got a lot of stuff hanging off the same power bus.
To me, the really helpful thing about thinking about it that way is it always gives you multiple avenues to attack a problem."
