Radiated and Conductive Coupling

Methods of Noise Coupling

Coupling in cable harnesses, transmission lines, and PCB traces may occur via capacitive and inductive transfer modes. Capacitive coupling is predominant at higher frequencies as result of high impedance to ground.
Inductive coupling between two currents within a closed loop system is predominant in low-series-impedance circuits and at low frequencies. Apart from the reactive transfer of RF energy, or interference, a resistive transfer may also happen through the voltage drop in a common reference path between two devices, circuits, or systems. A voltage drop across the common path caused by current flow in one circuit will appear as interference source signal. This interference current is propagated in a conducted manner along the transmission lines and is observed at the load terminal of adjacent circuits.
