📡 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.
