<p num="1"><br/><br/><br/>The invention relates to near-real-time recording and analysis of data <br/>relating to surface faults. The following steps are used: transmission of the <br/>signals to a pre-amplifier, conversion of the analogue signals to a continuous <br/>data stream of digital data, buffering the data stream in a first memory (A), <br/>filing the first memory (A) with k data points, copying the k data points of <br/>the first memory (A) to a second memory (B) in a short time between two <br/>digital data points with simultaneous refilling of the first memory (A) with <br/>new data, transformation of the copied data by means of wavelet transformation <br/>and filtering or modification of the resulting wavelet coefficients, <br/>comparison of the measured parameters with a reference parameter, whereby a <br/>determined fault signal can be unambiguously allocated to the position of the <br/>fault.<br/>
