1785 . MODELS FOR GENERATION 1 / f NOISE

Simple analytically solvable models are proposed exhibiting 1/f spectrum in wide range of frequency. The signals of the models consist of pulses (point process) which interevent times fluctuate about some average value, obeying an autoregressive process with very small damping. The power spectrum of the process can be expressed by the Hooge formula. The proposed models reveal possible origin of...

"1/f noise" in music: Music from 1/f nOiSe

The spectral density of fluctuations in the audio p wer of many musical selections and of English speech varies approximately s l/f (f is the frequency) down to a frequency of 5X 10 -4 Hz. This resultAmplies that he audio-power fluctuations are correlated over all times in the same manner as "l/f noise" in electronic components. The frequency fluctuations of music also have a 1/f spectral densi...

In order to predict extinction risk in the pres variability, fluctuating parameters may be rep stochastic models with different levels of varia the process of parameter estimation for three each other, and with autoregressive noise mo a model time-series (length, T) of populatio variance and the expected extinction risk for implication of assuming an incorrect noise m necessary to do so in term...

Point Process Models of 1/f Noise and Internet Traffic

We present a simple model reproducing the long-range autocorrelations and the power spectrum of the web traffic. The model assumes the traffic as Poisson flow of files with size distributed according to the power-law. In this model the long-range autocorrelations are independent of the network properties as well as of inter-packet time distribution.

Age-Related Changes in 1/f Neural Electrophysiological Noise.

Aging is associated with performance decrements across multiple cognitive domains. The neural noise hypothesis, a dominant view of the basis of this decline, posits that aging is accompanied by an increase in spontaneous, noisy baseline neural activity. Here we analyze data from two different groups of human subjects: intracranial electrocorticography from 15 participants over a 38 year age ran...
