9265505b 59/// \class AliMUONDigitizerV3
4ce497c4 60/// The digitizer is performing the transformation to go from SDigits (digits
61/// w/o any electronic noise) to Digits (w/ electronic noise, and decalibration)
62///
63/// The decalibration is performed by doing the reverse operation of the
64/// calibration, that is we do (Signal+pedestal)/gain -> ADC
65///
66/// Note also that the digitizer takes care of merging sdigits that belongs
67/// to the same pad, either because we're merging several input sdigit files
68/// or with a single file because the sdigitizer does not merge sdigits itself
69/// (for performance reason mainly, and because anyway we know we have to do it
70/// here, at the digitization level).
