White noise has to do with energy and it is equal energy for each frequency. All frequencies across the human audible spectrum are represented by equal amounts of energy. Pink noise is all about octaves and pink noise has equal energy per octave. Octave bands are how we hear music and sounds. When we hear, we hear in octaves.
ngis white noise. Unless otherwise speci ed, we usually initialize with Y 0 = 0. If f ngis Gaussian white noise, then we have a Gaussian random walk. The random walk model is a special case of AR(1) with ˚ 1 = 1. The stochastic di erence equation in M5 has an exact solution, Y n = Xn k=1 k: We can also call Y 0:N an integrated white noise A vector is white noise if. its components each have a probability distribution with zero mean and finite variance, and are statistically independent. More specifically you ask about additive Gaussian white noise. I assume we can take zero mean and finite variance as a given, so that leaves additivity, independence and normality. Fundamentally, the benefit of pink noise is that it tends to get softer and less abrasive as the pitch gets higher. The lower frequencies are louder, and the higher frequencies become easier on the ears. Pink noise shows up in many different places in nature, which makes it seem a bit more natural to most people's ears than white noise.2 Image Denoising with Gaussian-only Noise A generic model for signal-independent, additive noise is b = x+ ; (2) where the noise term follows a zero-mean i.i.d. Gaussian distribution i˘N 0;˙2. We can model the noise-free signal x 2RN as a Gaussian distribution with zero variance, i.e. x i ˘N(x;0), which allows us to model b as a Gaussian.
