Methods and systems for providing a noise signal

Providing a noise signal comprises providing a first signal corresponding to a first band of a frequency spectrum of the noise signal and providing a first signal low corresponding to the first band of the freguency spectrum of the noise signal. Next, providing a noise signal comprises providing a s...

Zusammenfassung:Providing a noise signal comprises providing a first signal corresponding to a first band of a frequency spectrum of the noise signal and providing a first signal low corresponding to the first band of the freguency spectrum of the noise signal. Next, providing a noise signal comprises providing a second signal corresponding to a second band of the frequency spectrum of the noise signal, the second signal based on the first signal low. And finally, the first signal and the second signal are summed to provide the noise signal.
