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