Colours of noise fractals and applications

Due to uncertainty in it, noise prevents exact prediction of the future from the past. Noise is generally described by spectral densities of certain functional dependence on frequency. Years of research revealed relations between natural phenomena and noise spectral distributions of either man-made or natural sources of different spectral density signal content. However, since many random functions of noise appear in nature and in technology in power spectra and power law relations, certain categories of noise spectral density distributions are generally described as powers of frequency¸ being grouped in such a way that each one represents certain specific natural and man-made phenomena. On the other hand, most of the natural phenomena have fractal dimensions that combine together spectral behaviour that occurs in reality as can be seen by measurements results. The paper shows these functional descriptions of noise in terms of colours and their combination with fractals theories, which enable development of advanced technologies.
