Engineering with EMC Awareness
Any electromagnetic or radio frequency energy that unintentionally disturbs the functionality of an electrical or electronic equipment is termed as Electromagnetic Interference (EMI). This interfering energy can be produced by a device or equipment itself or by other devices within close proximity. But if the equipment can function without loss in quality or reliability under influence of such an EMI, then the equipment is said to have Electromagnetic Compatibility (EMC) or to be under EMI control. Some common examples of Electromagnetic Interference (EMI) are
- Surge & Electrostatic Discharge (ESD)
- RF electromagnetic field disturbances (both conducted & radiated)
- Electrical Fast Transients (EFT)
