Abstract
Pink (1/f-) noise is one of the most common behaviors of biosystems. This paper is devoted to clarifying the stochastic answer given to white-noise excitation of bio-systems.
It is assumed that a living system in general is a bifurcative self-organizing system, and has cyclic symmetry with infinite degrees of freedom, and stationary random stochastic processes characterize their dynamism.
We show that this bifurcation characterizes all levels of bioactivity, and the white-noise excited biosystem has a filter function, and generates a pink-noise spectrum.
Environmental white-noise electromagnetic excitation (like ‘electrosmog’ in general) is filtered by the biosystem, and it gives a characteristic pink-noise answer-signal to this excitation.
