Electromagnetic Interference is a phenomenon in which electronic devices upset each other’s operation. Computers, television receivers, telephone sets, high-fidelity sound equipment, and certain medical devices can malfunction because of strong radio-frequency fields such as those from a nearby broadcast transmitter. The EMI is usually the result of improper or ineffective shielding in the affected device or system. Abbreviation, EMI.
