Electromagnetic compatibility

Electromagnetic compatibility (EMC) is achieved when a device functions satisfactorily in its electromagnetic environment without introducing intolerable disturbances. Electromagnetic interference (EMI) is the degradation in a device's performance due to these fields which make up the electromagnetic environment. Sources of EMI are identified, and the three common means used to control or suppress it, namely, grounding, shielding, and filtering are discussed. Other useful techniques for minimizing and controlling EMI are outlined.>
