Spectra of geomagnetic pulsations Pc1 of complex shape and simulation of their generation process

Results of detailed studies of the spectra of the wave packets of geomagnetic pulsations Pc1 of very complex shape are described. The extensive experimental data used revealed new features of the spectra of these signals and of the process of their generation. In addition, a theoretical simulation of this process was carried out. The results obtained are compared with the data from the analysis of spectra of signals of relatively simple shape, previously published by the authors.
