EMC

Electromagnetic Compatibility, also known as EMC, is the interaction of electrical and electronic equipment with its electromagnetic environment, and with other equipment. All electronic devices have the potential to emit electromagnetic fields. With the proliferation of electronic devices into everyday life - TVs, washing machines, electronic ignitions, traffic lights, mobile phones, ATMs, anti-theft tags, to name but a few - there is therefore a huge potential for devices to interfere with each other.

EMC, or Electromagnetic Compatibility, is the ability of a device to operate in an environment with other devices without affecting those devices. EMI, or Electromagnetic Interference, is when the electromagnetic output of a device disrupts the operation of another device.

Many people use EMC and EMI interchangeably as they both determine whether a device can coexist with other devices. EMC testing examines a product’s radio frequency (RF) emissions, and EMI testing its immunity to RF.
