Aiming at the problems of poor decomposition quality and the extraction effect of a weak signal with strong noise by empirical mode decomposition (EMD). a novel fault diagnosis method based on cascaded adaptive second-order tristable stochastic resonance (CASTSR) and EMD is proposed in this paper. In the proposed method. low-frequency interference components are filtered by using high... https://www.spidertattooz.com/ZWO-ASI178MC-CMOS-Astrophotography-Camera/
