What is Electromagnetic Interference (EMI)?
Electromagnetic interference (EMI) is a phenomenon that occurs when the operation of an electronic device is disturbed by an electromagnetic (EM) field and typically occurs when the device is close to an EM field, which disrupts the radio frequency spectrum. EMI is a common issue for electronic components used in various industries, such as military, defence, communication systems, appliances, and aerospace.
EMI can arise from various sources, both natural and man-made. It can take on multiple characteristics dependent upon its source as well as the nature of whatever mechanism is giving off the interference.
