| Abstract: | In the field of machinery condition monitoring and fault diagnosis, the theory of cyclostationary is an important tool for signal analysis and processing. In this paper, based on the theory of second order cyclostationary, two methods of cyclic periodogram are introduced and explained. One of the methods, Time Smoothed Cyclic Periodogram (TSCP), is used to diagnose signals from a vibrating bearing system. Compared with the result by the classical power spectral density analysis, TSCP is better for the diagnosis of bearing |
