21//_________________________________________________________________________
22// Utility Class for handling Raw data
23// Does all transitions from Digits to Raw and vice versa,
24// for simu and reconstruction
25//
26// Note: the current version is still simplified. Only
27// one raw signal per digit is generated; either high-gain or low-gain
28// Need to add concurrent high and low-gain info in the future
29// No pedestal is added to the raw signal.
