What is Electromagnetic Interference?
Electromagnetic interference (EMI) is a phenomenon that occurs when the operation of an electronic device is disturbed by an electromagnetic field and typically occurs when the device is close to an electromagnetic field, which disrupts the radio-frequency spectrum. This can also be referred to as radio-frequency interference (RFI).
EMI can arise from various sources, both natural and man-made, and it can take on a variety of characteristics dependent upon its source as well as the nature of whatever mechanism is giving off the interference.
