Electromagnetic Interference

Electromagnetic interference (EMI) is unwanted electromagnetic energy that disrupts the normal operation of electronic devices and circuits. It occurs when electromagnetic fields from one device interfere with the signals or functionality of nearby electronic equipment, causing issues like signal distortion, data corruption, or device malfunction. EMI can originate from both natural sources (like lightning) and man-made sources (like motors, switching circuits, or radio transmitters), and is a critical consideration in electronic design requiring proper shielding and filtering techniques.
