Abstract
In this paper we are concerned with the problem of picking out the useful signal from noisy voltage recordings in geoelectrical prospecting. The voltage time series, recorded at the measuring probes of the electrodic array is made up of the sum of a deterministic component, the response of medium to the energizing current, and a random noise component.
