Class FMHarmonicSquareWave

java.lang.Object

toxi.math.waves.AbstractWave

toxi.math.waves.FMHarmonicSquareWave

public class FMHarmonicSquareWave
extends AbstractWave

Frequency modulated bandwidth-limited square wave using a fourier series of harmonics. Also uses a secondary wave to modulate the frequency of the main wave.

Note: You must NEVER call the update() method on the modulating wave.

 AbstractWave fmod)

Method Details

pop

public void pop()

Overrides:

pop in class AbstractWave

push

public void push()

Overrides:

push in class AbstractWave

reset

public void reset()

Resets this wave and its modulating wave as well.

Overrides:

reset in class AbstractWave

See Also:

• AbstractWave.reset()

update

public float update()

Progresses the wave and updates the result value. You must NEVER call the update() method on the modulating wave since this is handled automatically by this method.

Specified by:

update in class AbstractWave

Returns:

current (newly calculated) wave value
