/*
  Class for creating of the sumable digits and digits from MC data
  //
  The input :  ideal signals (Hits->Diffusion->Attachment -Ideal signal)
  The output:  raw digits

  Effect implemented:
  1. Pad by pad gain map
  2. Noise map
  3. The dead channels identified  - zerro noise for corresponding pads
     In this case the outpu equal zerro
