Constructor & Destructor Documentation

RtNoise()

RtNoise::RtNoise ( qint32  p_iMaxSamples, FIFFLIB::FiffInfo::SPtr  p_pFiffInfo, qint32  p_dataLen, QObject *  parent = 0  )

explicit

Creates the real-time covariance estimation object.

Parameters

[in]	p_iMaxSamples	Number of samples to use for each data chunk.
[in]	p_pFiffInfo	Associated Fiff Information.
[in]	parent	Parent QObject (optional).

Definition at line 64 of file rtnoise.cpp.

~RtNoise()

RtNoise::~RtNoise

(

)

Destroys the Real-time noise estimation object.

Definition at line 95 of file rtnoise.cpp.

Member Function Documentation

append()

void RtNoise::append

(

const Eigen::MatrixXd &

p_DataSegment

)

Slot to receive incoming data.

Parameters

[in]

p_DataSegment

Data to estimate the spectrum from -> ToDo Replace this by shared data pointer.

Definition at line 150 of file rtnoise.cpp.

hanning()

QVector< float > RtNoise::hanning ( int  N, short  itype  )

protected

Definition at line 104 of file rtnoise.cpp.

isRunning()

bool RTPROCESSINGLIB::RtNoise::isRunning ( )

inline

Returns true if is running, otherwise false.

Returns

true if is running, false otherwise.

Definition at line 190 of file rtnoise.h.

run()

void RtNoise::run ( )

protectedvirtual

The starting point for the thread. After calling start(), the newly created thread calls this function. Returning from this method will end the execution of the thread. Pure virtual method inherited by QThread.

Definition at line 188 of file rtnoise.cpp.

SpecCalculated

void RTPROCESSINGLIB::RtNoise::SpecCalculated ( Eigen::MatrixXd  )

signal

Signal which is emitted when a new data Matrix is estimated.

Parameters

[out]

start()

bool RtNoise::start ( )

virtual

Starts the RtNoise by starting the producer's thread.

Returns

true if succeeded, false otherwise.

Definition at line 161 of file rtnoise.cpp.

stop()

bool RtNoise::stop ( )

virtual

Stops the RtNoise by stopping the producer's thread.

Returns

true if succeeded, false otherwise.

Definition at line 175 of file rtnoise.cpp.
