10// Utility Class for handling Raw data
11// Does all transitions from Digits to Raw and vice versa,
12// for simu and reconstruction
13//
14// Note: the current version is still simplified. Only
15// one raw signal per digit is generated; either high-gain or low-gain
16// Need to add concurrent high and low-gain info in the future
17// No pedestal is added to the raw signal.
