A narrow-band high frequency amplitude modulation as a model of vibration signal is considered. Use of Hilbert transform for the demodulation of periodically non-stationary random signal (PNRS) is discussed. Relations for spectral and covariance comp

It is shown that the models of gear pair vibration, proposed in literature, are particular cases of the bi-periodically correlated random processes (BPCRPs), which describe its stochastic recurrence with two periods. The possibility of vibration and

The periodical non-stationary random signal (PNRS), which is a superposition of amplitude and phase stochastically modulated harmonics with multiple frequencies, is considered. It is assumed that the modulation spectrum is concentrated in a band widt
