It is shown that the analysis of the dynamics of auto-and cross-correlation temporary signals of flux radio spectral density of quasi-stellar objects that are fixed at the same time at frequencies 2.7 GHz and 8.1 GHz, using the method of flicker -noise spectroscopy (FNS) allows not only to establish the individual characteristics of accretion of the substance in these objects, but also to identify qualitatively distinct mechanisms of its generation. The possibilities of use of two-parameter FNS cross-correlation in the analysis of the effects of frequency and phase synchronization realized in the radio emission of quasars and 0215p015 and 1641p399 at different frequencies are demonstrated. It is established that the loss of synchronization in the event of quasar 1641p399 due to increase in the intensity of the random components of the signals in the radio flux in the high-frequency area, which leads to the «deformation” of 3d structure of the cross-correlation.
