This chapter determines the ways in which various emissions are coupled into the devices, equipment and systems. The coupling is the inductance due to magnetic flux in the Culprit inducing noise on the Victim wire. When several antennas are stacked on the same mast, separating the antennas may be the only means of solving the intermodulation problem. Common Mode Rejection Ratio assists circuit designers on deciding whether to implement shielding, twisted pair or both to reduce noise on signal lines. The objective of EMC is to allow the equipment or device to operate satisfactorily in a noisy environment. This is commonly called immunity. A four‐section filter can have a great deal of attenuation. One of the most destructive sources of EMI is lightning, which consists of a high‐energy pulse rich in harmonics. At high frequencies, the center of the conductor is unnecessary due to skin effect.
