    104 An important point is the difference between the pulse shapes of the calibration and Cherenkov signals. It has to be ensured that the calibration factor between the reconstructed charge in FADC counts and photo electrons for calibration events can be applied to Cherenkov signals.
     105An important point is the difference between the pulse shapes of the calibration and Cherenkov signals. It has to be ensured that the
     106computed calibration factor between the reconstructed charge in FADC counts and photo electrons for calibration events
     107is valid for signals from Cherenkov photons.

    107110\subsection{Applicability for Different Sampling Speeds / No Pulse Shaping.}
    108 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 about 2 ns FWHM of Cherenkov pulses. To acquire the pulse shape an artificial pulse shaping to about 6.5 ns FWHM is used. Thereby also more LONS is integrated that acts as noise.
     111The current read-out system of the MAGIC telescope~\cite{Magic-DAQ} with 300~MSamples/s is relatively slow compared to the fast pulses of
     112about 2\,ns FWHM of Cherenkov pulses.
     113To acquire the pulse shape an artificial pulse shaping to about 6.5\,ns FWHM is used. Thereby also more night sky background light
     114is integrated which acts as noise.

    110116For 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.
