"WebFeb 3, 2024 · I am not a very experienced user in Matlab. I am doing time-frequency analyses on my EEG data, looking at low frequencies. To do so, I need to get rid of 1/f (pink noise), but I am not sure how to do it. I am using polyfit function to estimate the 1/f slope, but I don't know if I am doing it correctly, and I don't know what to do next. " - Pink noise in matlab

Webpink noise is essentially 1 / f k - while it well diminishes by about x dB per octave in log scale, where close to zero, it would approaches infinity near zero. In real life what we generally tend to refer to as pink noise, such as flicker are not actually true 1/f yet are dominant at some key frequency close to DC in someway. – Dipan Mehta WebPink noise, 1 ⁄ f noise or fractal noise is a signal or process with a frequency spectrum such that the power spectral density (power per frequency interval) is inversely proportional to the frequency of the signal. In pink noise, each octave interval (halving or doubling in frequency) carries an equal amount of noise energy.. Pink noise sounds like a waterfall.
