 Figure \ref{fig:shape_fit_TDAS} shows the simulated signal pulse shape of a typical MC event together with the simulated FADC slices of the signal pulse plus noise. The digital filter has been applied to reconstruct the signal size and timing. Using this information together with the average normalized MC pulse shape the simulated signal pulse shape is reconstructed and shown as well.

 The digital filter is a sophisticated numerical tool to fit the read-out FADC samples with the expected wave form taking the autocorrelation of the noise into account. In order to cross-check the results a pulse shape fit has been implemented using the root TH1::Fit routine. For each event the FADC samples of each pixel are filled into a histogram and fit by the expected wave form having the time shift and the area of the fit pulse as free parameters. The results are in very good agreement with the results of the digital filter. 
 
 Figure \ref{fig:probability_fit} shows the distribution of the fit probability for simulated MC pulses. Both electronics and NSB noise are simulated. The distribution is mainly flat with a slight excess in the very lowest probability bins.
