This is the startpoint for the further development of the FADC system. This implementation of the class MFadc is based on the implementation of the class MTRigger (see ../include-MTrigger ).

8// This is a class to simulate the FADC.

25//==========
26// MFadc
27//
28// The simulation of the Flash ADC system for the MAGIC teleskop is done with
29// this class.
30// So all methods concerning the FADC System should be done inside this
31// class.
32//
33// The Idea is to (in)put the data of the photo electrons into the class and
34// generate the response (output) of the FADC to that input. Response means
35// in this sense the ADC values of the different time slices for all pixels
36//
37// The pixelisation is done by the camera program of Jose Carlos.
38//
39// This class is closly connected to the MTrigger classs. So some of the
40// values defined in MTriggerDefine.h are also used by this class.
41//
42// But a lot of other stuff is defined here.
43//
44// --> Frist of all the WIDTH of the time slice of one FADC slice
45// this is 3.33333 nsec.
46//
47#define WIDTH_FADC_TIMESLICE (50./15.) // this means 3.33 nsec
48//
49// --> Second the number of slices to fill in MFADC. This must by
50// connected to the MTrigger class. The time of interest must be
51// equal in both classes.
52//
53#define SLICES_MFADC (TOTAL_TRIGGER_TIME / WIDTH_FADC_TIMESLICE)
54//
55// --> like the trigger the FADC value will also have a standard response
56// to one single Photo electron. This response is binned with smaller
57// bins. The WIDTH of that response function is done here.
58//
59#define SUBBINS 5.
60#define WIDTH_RESPONSE_MFADC (WIDTH_FADC_TIMESLICE / SUBBINS ) // 5 sub-bin in one FADC slice
