What is Electromagnetic Interference (EM)?
Electromagnetic Interference (EMI) refers to electromagnetic disturbance that affects the performance of a device, equipment or system. Any device that transmit, distributes or processes any form of electrical energy can be a source of EMI if its operation generates conducted and/or radiated electromagnetic signals that can disrupt the performance of other equipment or systems that share the same environment. EMI can be a threat to public safety as it causes disruption to strategic infrastructure such as hospitals, underground rail transport, airports and military air bases. Many countries have introduced regulations on Electromagnetic Compatibility (EMC) to ensure that electrical/electronic systems operate without being susceptible to electromagnetic interference or being a source of interference to other systems. Trade Implications of EMI In United States, mandatory EMC control has been imposed on telecommunication as well as electrical and electronic equipment. These products, wheth
