Blog: The increasing threat of Electromagnetic Interference
Understand Electromagnetic Interference (EMI/RFI) filtering, Transient Voltage Suppression, and the basics of signal conditioning:
Electromagnetic interference (EMI) also called radio-frequency interference (RFI) is a disturbance generated by unwanted electrical signals from electronic devices or natural occurrences which may reduce the performance of the equipment and can even stop it from functioning.
It can impact various flight-critical applications including communication and military flight control systems, medical applications, and telecommunications.
Design engineers need a way to filter out the unwanted electrical signal, so it doesn't harm additional components. In order to protect modern electronic systems from the abundance of EMI sources in today’s environments, a combination of approaches are implemented: shielding, filtering, and reduction of EMI at the source (if possible).
