Measurements and Management of Power Line Communication
This App. Note provides recommendation on measuring power line communication signals on live wires and mitigation of communication collisions and other issues
What is EMI? NIST defines EMI as "“an electromagnetic disturbance that interrupts, obstructs, or otherwise degrades or limits the effective performance of electronics/electrical equipment.” Most conventionally, EMI is understood as undesirable high-frequency signals, and EMI filters as devices that suppress such signals while preserving the "good" ones.
