[Structure of the spectrum of dolphin communication signals].
Dynamics of changes in the thin structure of the spectrum of dolphin communication signals is studied using Furie algorythm of fast transformation. Computer analysis of whistle signals allows to obtain quantitative evaluations of spectral characteristics and shows that coding of information in dolphin communication signals may be carried out by controling of signal harmony power and multiplicative modulation of frequencies of the basic tone and harmony.
