WorkshopDemo
Class WorkshopProcess.ChannelDetector

java.lang.Object
  WorkshopDemo.WorkshopProcess.ChannelDetector

Enclosing class:

WorkshopProcess

 class WorkshopProcess.ChannelDetector
extends java.lang.Object

Since the detector may be running on several channels, make a sub class for the actual detector code so that multiple instances may be created.

Constructor Detail

WorkshopProcess.ChannelDetector

public WorkshopProcess.ChannelDetector(int channel)

Method Detail

pamStart

public void pamStart()

newData

public void newData(PamObservable o,
                    FFTDataUnit arg)

Performs the same funciton as newData in the outer class, but this time it should only ever get called with data for a single channel. For the first few calls, it just updates the background by taking a straight mean of the energy values. After that it calculates a decaying average of the background.

Parameters:

o -

arg -

energySum

private double energySum(Complex[] fftData,
                         int bin1,
                         int bin2)

startDetection

private void startDetection(FFTDataUnit dataUnit,
                            double energy)

continueDetection

private void continueDetection(FFTDataUnit dataUnit,
                               double energy)

endDetection

private void endDetection()
