Detailed Description

This class defines a low pass filter of order 1, with a response in Fourier space with following form:

$F(f) = \frac{1}{1 + j \frac{f}{f_{0}}}$

where $f_{0}$ is the cut frequency.

Constructor & Destructor Documentation

GETFilterLow::GETFilterLow	(	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 GETFilterCut::cut_frequency, GETObject::GetSampleDim(), GETObject::GetTimeStep(), GETFilter::Init(), and UpdateFilter().

GETFilterLow::GETFilterLow	(	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 GETFilterCut::cut_frequency, GETFilter::Init(), and UpdateFilter().

GETFilterLow::GETFilterLow ( const GETFilterLow & proc )

Copy constructor.

Parameters

proc	object to copy

References GETFilterCut::cut_frequency, GETFilterCut::GetCutFrequency(), GETFilter::GetFilter(), GETFilter::Init(), and UpdateFilter().

GETFilterLow::~GETFilterLow ( )

virtual

Destructor.

Member Function Documentation

GETFilterLow::ClassDef	(	GETFilterLow	,
		0
	)

for use within ROOT.

GETFilterLow::GObject ( GETFilterLow )

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 GETFilterLow::UpdateFilter ( )

virtual

Compute the filter sample.

Reimplemented from GETFilterCut.

References GETFilterCut::cut_frequency, GETProcess::GetDimension(), GETFilter::GetFilterPtr(), and GETProcess::GetSamplingTime().
