    112 \subsection{Applicability for Different Sampling Speeds / No Pulse Shaping.}
    113112
    114 The current read-out system of the MAGIC telescope~\cite{Magic-DAQ} with 300~MSamples/s is relatively slow compared to the fast pulses of
    115 about 2\,ns FWHM of Cherenkov pulses.
    116 To acquire the pulse shape an artificial pulse shaping to about 6.5\,ns FWHM is used. Thereby also more night sky background light
    117 is integrated which acts as noise.
    118 
    119 For 2 ns FWHM fast pulses a 2 GSamples/s FADC provides at least 4 sampling points. This permits a reasonable reconstruction of the pulse shape. First prototype tests with fast digitization systems for MAGIC have been successfully conducted \cite{GSamlesFADC}. The signals have been reconstructed within the common MAGIC Mars software framework.
    120 
    121 
    122 \subsection{CPU Requirements}
    123 
    124 Depending on the reconstruction algorithm the signal reconstruction can take a significant amount of CPU time.
    125 Especially the more sophisticated signal extractors can be time consuming which search for the position of the Cherenkov signals
    126 in the recorded FADC time slices and perform a fit to these samples. At any case, the extractor should not be significantly slower than
    127 the reading and writing routines of the MARS software.
    128 
    129 Thus, for an online-analysis a different extraction algorithm might be chosen than for the final most accurate
    130 reconstruction of the signals offline.
    131 
    132 \subsection{Treatment of Calibration Pulses}
     113\subsection{Intrinsic Differences between Calibration and Cosmics Pulses}
    133114
    134115The calibration pulse reconstruction sets two important constraints to the signal extractor:
