Constructor Detail

NoiseProcess

public NoiseProcess(NoiseControl noiseControl)

Method Detail

newSettings

protected void newSettings()

Call when settings dialog has been used or after initialisation

notifyModelChanged

public void notifyModelChanged(int changeType)

Overrides:

notifyModelChanged in class PamProcess

setMeasurementTimes

private void setMeasurementTimes(long currentTime)

Work out a new set of measurement times.

These are initially set as evenly spread between now and the measurement interval. Then add some jitter at random to each.

Parameters:

currentTime - current sample number.

findDataSource

private void findDataSource()

getChannelGains

private double getChannelGains(int iChan)

Work back through the data model and work out the accumulated gain of all upstream processes.

Returns:

total gain of upstream processes as a factor (not dB).

pamStart

public void pamStart()

Description copied from class: PamProcess

Called for each process to tell it to start (may not be necessary for processes which are listening for data anyway.

Specified by:

pamStart in class PamProcess

pamStop

public void pamStop()

Description copied from class: PamProcess

Stops the process.

Specified by:

pamStop in class PamProcess

newData

                    PamDataUnit arg)

Overrides:

newData in class PamProcess

newFFTData

private void newFFTData(FFTDataUnit fftDataUnit)
