Detailed Description

This class defines a simple response function for the GET input signal. The response is defined by the sample for convolution / deconvolution of input (test) / output signals.

Constructor & Destructor Documentation

GETResponse::GETResponse

(

GETObject &

obj

)

Constructor: the dimension of the first channel of the object is used for the process definition. At initialization, the default response function is set to reproduce the input signal (full band filter).

Parameters

obj	a core object of the GET system

References GETObject::GetSampleDim(), GETObject::GetTimeStep(), and Init().

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

Constructor. At initialization, the default response function is set to reproduce the input signal (full band filter).

Parameters

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

References Init().

GETResponse::GETResponse

(

const GETResponse &

proc

)

Copy constructor.

Parameters

proc	object to copy

References GetResponse(), and response_fct.

GETResponse::~GETResponse ( )

virtual

Destructor.

const GETSample & GETResponse::GetResponse ( ) const

GETResponse::GObject ( GETResponse  )

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 GETResponse::Init ( u_int  n, double  dt  )

virtual

Initialization of response function sample.

Parameters

n	sampling size of the function
dt	sampling time step

Reimplemented from GETProcess.

Reimplemented in GETResponseFct.

GETSample * GETResponse::ProcessSample ( GETChannel &  channel, u_short  info  )

virtual

This function process the argument channel and stores the result in the internal sample. The channel sample that is processed depends on the info argument:

• if info == GET::signalTst, the input test sample is convoluted with the response function
• if info == GET::signalOut, the output sample is deconvoluted with the response function The function returns the internal result sample pointer. In case of error, the result is a NULL pointer.

For the base response function class, the processing is the convolution or the deconvolution with the response function sample data.

Parameters

channel	GET system channel to be processed
info	additional optional information (sample signal identifier)

Implements GETProcess.

Examples:

TestChannel.C.

References GETChannel::OutSample(), GETProcess::result_sample, GET::signalOut, GET::signalTst, and GETChannel::TstSample().

Referenced by GETChannel::ProcessOutFromTst(), GETChannel::ProcessRecFromOut(), and ProcessSample().

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

inlinevirtual

This function process the input sample channel and stores the result in the result sample (convolution with response function). The channel argument is provided if processing (from derived classes) may be affected by GET core objects properties. The function returns the (argument) result sample sample pointer. In case of error, the result is a NULL pointer.

For the base filter class, the processing is the convolution with the response function sample data (see function with bool argument for deconvolution).

Parameters

sample	input sample to be processed
result	sample where result should be stored
channel	GET system channel to be processed

Implements GETProcess.

References ProcessSample().

GETSample * GETResponse::ProcessSample ( GETSample &  sample, GETSample &  result, GETChannel &  channel, bool  inv  )

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 channel argument is provided if processing (from derived classes) may be affected by GET core objects properties. The function returns the (argument) result sample sample pointer. In case of error, the result is a NULL pointer.

For the base response function class, the processing is the convolution or the deconvolution with the response function sample data.

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 to be processed
inv	deconvolution instead of convolution

References response_fct.

void GETResponse::Reset ( )

virtual

Function resetting the response function.
