    Reduction in electromagnetic interference can be observed by comprehending the techniques of noise coupling. Noise coupling mainly includes conductive coupling, inductive or capacitive coupling, radiated coupling.

    The noise which is transmitted by electromagnetic field & then received by an antenna effect is known as radiated noise. Radiated noise coupling deals with the reception or transmission of propagating electromagnetic energy in the circuit.

    It is said to yield the far-field effect while inductive and capacitive couplings provide near field effects. However, Annecoic chamber is used for the elimination of radiated electromagnetic interference.
