Detailed Description

This class defines a filter adapted for a refence signal.

It is based on the optimal filter, considering constant noise spectral density, corresponding to the reference signal PSD at cut frequency.

The picture below shows the construction of such a filter for a Gauss reference signal.

Constructor & Destructor Documentation

GETFilterRef::GETFilterRef	(	GETObject &	obj,
		double	fcut = `0.`
	)

Constructor. The dimension of the first channel of the object is used for the process definition.

Parameters

obj	a core object of the GET system
fcut	cut frequency

References cut_frequency.

GETFilterRef::GETFilterRef	(	u_int	n = `0`,
		double	dt = `0.01`,
		double	fcut = `0.`
	)

Constructor.

Parameters

n	sampling size of the channels
dt	sampling period (us)
fcut	cut frequency

References cut_frequency.

GETFilterRef::GETFilterRef ( const GETFilterRef & proc )

Copy constructor.

Parameters

proc	object to copy

References cut_frequency.

GETFilterRef::~GETFilterRef ( )

virtual

Destructor.

	)

for use within ROOT.

double GETFilterRef::GetCutFrequency ( )

inline

Return the cut frequency.

References cut_frequency.

GETSample & GETFilterRef::GetReference ( )

inline

Return the reference signal sample.

References ref_signal.

GETFilterRef::GObjectV ( GETFilterRef )

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.
