EMI (Electromagnetic Interference)

Electromagnetic Interference (EMI) refers to unwanted noise or disturbances caused by electromagnetic signals from nearby sources that disrupt the normal operation of electronic devices. These disturbances can come from various sources such as cellphones, motors, or wireless networks, and may lead to errors, reduced performance, or malfunctions in electronic systems. EMI occurs because electronic devices emit and are sensitive to electromagnetic energy; when this energy overlaps or interacts, it can interfere with proper functioning. Engineers design devices with shielding and filtering to minimize EMI and ensure reliable operation in electromagnetic environments.
