//     implemented by Harald Kornmayer
//
//     This is a class to simulate the FADC. 
//     It assumes a special response of the PMT for one single Photo-electron.

//==========
//  MFadc 
//
//  The simulation of the Flash ADC system for the MAGIC teleskop is done with
//  this class. 
//  So all methods concerning the FADC System should be done inside this
//  class. 
//
//  The Idea is to (in)put the data of the photo electrons into the class and
//  generate the response (output) of the FADC to that input. Response means 
//  in this sense the ADC values of the different time slices for all pixels
//
//  The pixelisation is done by the camera program of Jose Carlos. 
//
//  This class is closly connected to the MTrigger classs. So some of the
//  values defined in MTriggerDefine.h are also used by this class. 
//
//  But a lot of other stuff is defined in MFadcDefine.h. 
//
//
