	Electromagnetic Interference (EMI) manifests as malfunctions at the component, equipment, subsystem and system level. Generally, EMI is an electrical disturbance from either a natural phenomenon (lightning, Electrostatic Discharge (ESD), etc.) or an electrical or electronic equipment that causes an undesired response (malfunction) in other equipment. These malfunctions can result in time consuming delays for investigation and troubleshooting to implement needed corrections. Electromagnetic Compatibility (EMC) looks at controlling those disturbances using installation ~~techniques~~ and other EMI and Radiofrequency Interference (RFI) reducing techniques that are implemented early in the design and installation of the equipment or system.
