Statistic description for fluctuations of the cyclically operating mechanism period

The frequency-chronometric experimental method to investigate dynamics of the round-robin machines and mechanisms of cyclic operation, is statistically described. Correlation function and frequency response of the method are obtained. On their basis the peculiarities of spectral filtration of signals are analysed measuring the fluctuations of round-robin mechanism period. It is shown using n-dimensional characteristics that the fluctuation period itself presents a nonmarkov random process.
