Electromagnetic interference (EMI) refers to the disruption of electronic devices caused by electromagnetic radiation emitted from other sources. This interference can affect the performance of various devices, including radios, televisions, and computers, leading to issues like static, distortion, or complete failure to operate. EMI can originate from natural sources, such as lightning, or man-made sources, like motors and power lines. To mitigate EMI, engineers often use shielding techniques, filters, and proper grounding in electronic designs. Understanding and managing EMI is crucial for ensuring the reliability and functionality of electronic systems, especially in sensitive environments like hospitals and communication networks.
