| 49 | Presently, the MAGIC telescope uses a 300~MHz FADC system to sample the transmitted and shaped signals from | 
|---|
| 50 | the captured Cherenkov light of air showers. | 
|---|
| 51 | In this note. different algorithms to reconstruct the signal from the read out samples | 
|---|
| 52 | are described and compared. Criteria for comparison are defined and used to judge the | 
|---|
| 53 | different extractors applied to calibration signals, cosmics and pedestals. At the end, | 
|---|
| 54 | extractors are recommended for the most conservative and the most advanced and demanding analyses. | 
|---|
| 55 | It is shown that the digital filter | 
|---|
| 56 | can be used to extract and fit single photo-electron pulses from the night sky background. | 
|---|
| 57 | The achievable time resolution has been derived as a function of the incident number of | 
|---|
| 58 | photo-electrons. | 
|---|
| 59 | %\begin{equation} | 
|---|
| 60 | %\Delta T_{\mathrm{cosmics}} \approx \sqrt{\frac{(2\,\mathrm{ns})^2}{<Q>/{\mathrm{phe}}} | 
|---|
| 61 | %+ \frac{(4.5\,\mathrm{ns})^2}{<Q>^2/{\mathrm{phe^2}}} + (0.2\,\mathrm{ns})^2} . \nonumber | 
|---|
| 62 | %\label{eq:time:fitprediction} | 
|---|
| 63 | %\end{equation} | 
|---|
| 64 | For galactic backgrounds an image cleaning threshold as low as 5~photo-electrons can be achieved | 
|---|
| 65 | without using the timing information and for rejecting 99.7\% of noise. |
