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