It is called electromagnetic interference that electrical-electronic and electromechanical systems mutually interact with the electromagnetic energy that is released when they are in operation or with the electromagnetic energy which exists in the environment and that these systems are deteriorated in operating performance or become totally inoperable. The sources that emit energy can be either natural or human. Examples of these resources:
- Transcripts (human structure)
- Electric motors (human structure)
- Circuit switching elements such as relays (human structure)
- Industrial RF sources (human structure)
- Spark ignition engines (human structure)
- Nuclear Electromagnetic Pulse – EMP (human structure)
- Lightning (natural) Electrostatic discharge (natural)
