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