<p>The signal resulting from an ECG is digitally processed in order to obtain a filter effect. The membrane signal can be obtained because of the mathematical connection between the ECG-signal, which is a mixed signal, and the membrane-signal. The Fourier transformation of the position function of the membrane signal determines the distance to the source of the particular signal, facilitating a three-dimensional representation of the sources of the signals.</p> |
