Detailed Description

This class defines a signal correction process, that inherits from the baseline correction and include a phase effect correction depending on the last cell read of the AGet chip.

The baseline correction dimension is the readout dimension of the GET system. The phase correction is in all cases a 512 data sample, since in the case of a smaller readout dimension (256 or 128), the 512 cells of the memory are used anyway.

The case of the 2-proton mode has to be processed in a different way (not yet implemented).

Constructor & Destructor Documentation

GETPhaseCorrection::GETPhaseCorrection

(

GETObject &

obj

)

Constructor. The dimension of the first channel of the object is used for the process definition. The baseline and phase samples are initialized to 0. Note that the phase correction is always computed on 512 data, even if the readout depth is 256 or 128.

Parameters

obj	a core object of the GET system

GETPhaseCorrection::GETPhaseCorrection	(	u_int	n = 0,
		double	dt = 0.01
	)

Constructor. The baseline and phase samples are initialized to 0. Note that the phase correction is always computed on 512 data, even if the readout depth is 256 or 128.

Parameters

n	sampling size of the channels
dt	sampling period (us)

GETPhaseCorrection::GETPhaseCorrection	(	const GETSample &	ped,
		const GETSample &	phase
	)

Constructor. The sample parameters (size and period) from the pedestal and the phase samples must be the same.

Parameters

ped	pedestal (baseline) sample
phase	phase correction sample

References SetPhaseSample().

GETPhaseCorrection::GETPhaseCorrection

(

const GETPhaseCorrection &

proc

)

Copy constructor.

Parameters

proc	object to copy

GETPhaseCorrection::~GETPhaseCorrection ( )

virtual

Destructor.

for use within ROOT.

const GETSample & GETPhaseCorrection::GetPhaseSample ( ) const

inline

Return the phase correction sample.

References phase_sample.

GETSample & GETPhaseCorrection::GetPhaseSample ( )

inline

Return the phase correction sample.

References phase_sample.

GETPhaseCorrection::GObject ( GETPhaseCorrection  )

private

Macro from GCpp library that defines the following functions:

• ClassName(): return the real class name of the object
• StaticClassName(): return the used class name of the object (that may be a base class of the real object).
• IsInstanceOf<T>(): return true if the current object is an instance of the template class name argument
• Clone(): return an allocated copy of the object.

GETSample * GETPhaseCorrection::ProcessSample ( GETSample &  sample, GETSample &  result, GETChannel &  channel  )

virtual

This function process the input sample channel and stores the result in the result sample (convolution or deconvolution of the response function, according to inv argument).

The function returns the (argument) result sample sample pointer. In case of error, the result is a NULL pointer.

Note

• The sample to be processed and the result sample can be the same object, in which case the initial sample is replaced by the processing result.
• The initial and result samples may be the same object, in which case the sample is replaced by the result.

Parameters

sample	input sample to be processed
result	sample where result should be stored
channel	GET system channel (no use in this class)

Reimplemented from GETBaselineCorrection.

References GETBaselineCorrection::baseline, GETChannel::GetLastCell(), and phase_sample.

void GETPhaseCorrection::SetPhaseSample ( const GETSample &  phase )

virtual

Set the phase correction sample.

Parameters

phase

phase correction sample
