    1818\subsection{Applicability for Different Sampling Speeds / No Pulse Shaping.}
     19The 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.
     20
     21For 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.

    3939resolution of 8 bit only, the signals are split into two branches with gains differing by a factor 10.
    4040One branch is delayed by 55\,ns and then both branches are multiplexed and consecutively read-out by one FADC.

    4242% The maximum sustained trigger rate could be 1 kHz. The FADCs feature a FIFO memory which allows a significantly higher short-time rate.
    4343% Obviously by doing this, more LONS is integrated and thus the performance of the telescope on the analysis level is degraded.
