What is EMC?


A product achieves electromagnetic compatibility (EMC) when it can operate satisfactorily in its intended environment without generating electromagnetic interference, while at the same time not being affected by interference from that environment.

Three factors must be present for electro~magnetic jnterference (EMI) to occur, namely;

  • a source or culprit of electromagnetic energy

  • a medium or coupling path through which the energy is transmitted

  • a receptor or victim that suffers adverse effects.



Coupling Path



The coupling path can be either radiated (a true electromagnetic wave) or conducted (a current). Consequently, electromagnetic compatibility can be achieved by removing any of the above mentioned factors.
