Q: What is the difference between electromagnetic interference and electromagnetic compatibility?A: Electromagnetic interference (EMI) is the unwanted or harmful effect of electromagnetic fields or waves on the performance or functioning of an electronic device or system. Electromagnetic compatibility (EMC) is the ability of an electronic device or system to operate without causing or being affected by electromagnetic interference.

Q: What is the difference between shielding and grounding methods for EMI/EMC design?A: Shielding is the method of enclosing an electronic device or system with a conductive material that blocks or reflects the electromagnetic fields or waves from entering or leaving the device or system. Grounding is the method of connecting an electronic device or system to a common reference point such as the earth that provides a low impedance path for the unwanted currents or voltages induced by the electromagnetic fields or waves.
