What is EMI?  A formal definition of Electromagnetic Interference is that it is a malfunction of equipment caused by excessive high-frequency signals, either radiated (via air), or conducted (via wires).  Often it is also called RFI - Radio Frequency Interference.  Most conventionally, EMI is understood as undesirable high-frequency signals, and EMI filters as devices that suppress such signals while preserving the "good" ones.
