Electromagnetic Interference (EMI) is the presence of unwanted electromagnetic energy which has the potential to cause disturbances in electronic devices. The effects of electromagnetic interference is particularly troublesome for printed circuit board (PCB) designed for high frequency RF circuits. The components on a PCB may be digital or analog. Transmission lines connecting the two different sections are used to transmit signals back and forth. Unfortunately, as frequency increases and signals are enhanced, noise related to those frequencies is also enhanced, thus creating EMI. In terms of propagating path, EMI is classifies into conducted EMI and radiated EMI. The conducted EMI results from that the radiated signal stick on the power line and hard to detect and recognize. Therefore, it is necessary to build the causes and effects methodology by way of the correct measurement to maintain the electromagnetic compatibility (EMC), to target the electromagnetic interference, and to detect radio frequency interference(RFI). Electronic systems are expected to operate normally within a given environment without internally or externally radiating excessive amounts of electromagnetic energy. In this state, they are called electromagnetically compatible (EMC).
