?? What is EMC?

EMC stands for Electromagnetic Compatibility, a field focused on ensuring that electrical and electronic devices can operate together without interference. It involves two main components:

• Emission Control: Preventing devices from generating electromagnetic interference (EMI) ??.
• Immunity: Ensuring devices can withstand external EMI without malfunctioning ??.

Imagine listening to the radio ?? while charging your phone. Without proper EMC design, the charger could interfere, causing static noise. EMC ensures harmony among devices.
