eb7e0771 1/** @file Altro.C
2 * @brief The Altro class implements the Altro digital Chain in C++
3 *
4 * This Class represents a C++ version of the ALTRO. For a complete Documentation of the Altro
5 * Look at : http://ep-ed-alice-tpc.web.cern.ch/ep-ed-alice-tpc/altro_chip.htm\n
6 * Due to the fact that the real ALTRO constantly samples in between the recorded events,
7 * it has the knowledge on what happened in the period. This affects the BSL1, TCF and BSL2 module.
8 * In the BSL1 the ALTRO follows slow baseline drifts e.g. temperature change, the TCF has a infinite
9 * (IIR Filter) memory of "old samples" i.e. a cluster at the start of a readout cycle will be treated
10 * differently, and the BSL2 has a 8 step pipeline. The ALTRO Class can't emulate this behavior,
11 * since the data is not recorded.\n
