Constructor Detail

GaussWindow

public GaussWindow(int length)

Crate a Gauss window with the given length and a default sigma.

Parameters:

length - the length of the window, in samples (must be an odd number)

GaussWindow

public GaussWindow(int length,
           double prescalingFactor)

Crate a Gauss window with the given length and a default sigma, and apply a prescaling factor to each sample in the window.

Parameters:

length - the length of the window, in samples (must be an odd number)

prescalingFactor - prescaling factor

GaussWindow

public GaussWindow(int length,
           double sigma,
           double prescalingFactor)

Create a Gauss window with the given length and sigma.

Parameters:

length - the length of the window, in samples (should be an odd number)

sigma - the sigma coefficient in the Gauss curve. A good starting point is 100.

prescalingFactor - prescaling factor

Method Detail

initialise

protected void initialise()

Description copied from class: Window

The initialisation of the window array with multiplication factors corresponding to the specific windowing function. This needs to be implemented by each subclass.

Specified by:

initialise in class Window

toString

public String toString()

Overrides:

toString in class Object

main

public static void main(String[] args)
