Electromagnetic Compatibility (EMC) is the capability for multiple, diverse systems to operate in close proximity without causing or being subject to interference which can cause damaging effects to other technologies.
• EMI is the interference caused by an electromagnetic disturbance that affects the performance of a device. Sources of EMI can be environmental, such as electrical storms and solar radiation but more usually will be another electronic device or electrical system. If the interference is in the radio frequency spectrum it is also known as radio frequency interference or RFI.
• EMC is a measure of a device's ability to operate as intended in its shared operating environment while, at the same time, not affecting the ability of other equipment within the same environment to operate as intended.
