EMC

    Every electrical and electronic device emits electromagnetic waves as part of its normal operation. Laws, international standards, and country-specific regulations dictate that a device must not interfere with other devices through its radiation. Additionally, the device must be resilient to a certain level of surrounding interference radiation.
