Electromagnetic Compatibility and Interference

Electronic devices operating normally in their intended environment, without conducting or radiating excessive amounts of electromagnetic energy, or being susceptible to such energy from internal or external sources, are in the state of electromagnetic compatibility, or EMC. Electromagnetic interference, EMI, is radiated or conducted energy that adversely affects circuit performance, and thus disrupts a device's EMC. Many types of electronic circuits radiate or are susceptible to EMI and must be shielded to ensure proper performance. Establishing basic electromagnetic compatibility in any electronic device is important.
