Cyclostationarity by examples

This paper is a tutorial on cyclostationarity oriented towards mechanical applications. The approach is voluntarily intuitive and accessible to neophytes. It thrives on 20 examples devoted to illustrating key concepts on actual mechanical signals and demonstrating how cyclostationarity can be taken advantage of in machine diagnostics, identification of mechanical systems and separation of mechanical sources.
