Detailed Description

This class defines a filter adapted for Gauss signal.

It is based on the optimal filter, considering constant noise spectral density, corresponding to the reference signal PSD at cut frequency (see figure for GETFilterRef).

Examples:: TestChannel.C.

Constructor & Destructor Documentation

GETFilterGaus::GETFilterGaus	(	u_int	n = `0`,
		double	dt = `0.01L`,
		double	fcut = `0.L`,
		double	wid = `0.L`
	)

Constructor.

Parameters

n	sampling size of the channels
dt	sampling period (us)
fcut	cut frequency
wid	width (FWHM) of reference signal

References ref_fwhm, and UpdateFilter().

GETFilterGaus::GETFilterGaus ( const GETFilterGaus & proc )

Copy constructor.

Parameters

proc	object to copy

References ref_fwhm, and UpdateFilter().

GETFilterGaus::~GETFilterGaus ( )

virtual

Destructor.

Member Function Documentation

GETFilterGaus::ClassDef	(	GETFilterGaus	,
		0
	)

for use within ROOT.

double GETFilterGaus::GetReferenceFWHM ( )

inline

Return the reference signal width (FWHM).

References ref_fwhm.

GETFilterGaus::GObject ( GETFilterGaus )

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.

void GETFilterGaus::Init	(	u_int	n,
		double	dt
	)

virtual

Initialization of response function sample. If the analytical function is defined, the response function sample is computed.

Parameters

n	sampling size of the function
dt	sampling time step

Reimplemented from GETFilterRef.

References GETFilter::Init(), and UpdateFilter().

void GETFilterGaus::SetReference	(	double	wid,
		double	fcut = `0.L`
	)

virtual

Set the filter paremeters.

Parameters

wid	width (FWHM) of reference signal
fcut	cut frequency (not changed if 0)

References GETProcess::GetDimension(), GETFilter::GetFilter(), GETProcess::GetSamplingTime(), ref_fwhm, GETFilterRef::SetCutFrequency(), and UpdateFilter().

void GETFilterGaus::UpdateFilter ( )

virtual

Compute the reference and the filter sample.

Implements GETFilterRef.
