What is noise whitening?

The noise whitening module equalizes the spectrum of the signal, making it similar to the white noise spectrum. Noise whitening module works similarly to the automatic filter that enhances low level spectral components and attenuates high level ones.

What is noise whitening equation?

For the cases where the noise vector is not white, i.e., the co-variance matrix Ezz^H = Rzz , we then need to whiten the noise first by multiplying (Rzz)^(1/2) first to both sides of equation (1).

Why is the importance of noise whitening?

Because the hum of white noise is a pleasing sound for many people, it can help to induce a more relaxed state. By blocking out other sounds, white noise makes it easier to shut out the rest of the world and focus, as is necessary for practices like meditation that can aid sleep and reduce stress.

What is spectral whitening?

Spectral Whitening (sometimes called balencing or broadening) is a process usually applied post-migration to improve the resolution and appearance of seismic data and is a crude attempt to correct for frequency attenuation.
