by wavelet and Hilbert transforms or others methods. For two galvanically coupled electrodes comprising equal areas of the same material, when one event occurs on the surface of one electrode some charge associated with that event is consumed on the same electrode and some charge is consumed on the other electrode. In this case, one-half of the charge generated on one electrode is consumed on the same electrode, and one-half of the charge is consumed on the other electrode [21]. If the galvanic coupling between the two electrodes is realized with a zero-resistance ammeter, the coupling current can be measured simultaneously with the potential of the electrodes
