Abstract: Abstract The statistical characteristics of cyclostationary signals vary periodically in time. In the Gaussian (or second-order) case this property is typically related to the periodic autocovariance function. Thus, many classical methods for detection of cyclostationarity…

Abstract: Abstract Envelope analysis plays an essential role in fault diagnostics of rotating machinery. One popular method to attain the envelope spectrum is to integrate the spectral coherence over a chosen spectral frequency band. Considering the…

Abstract: The stability of the phase difference between two white-light continua, generated from the same 180-fs pulses at ≃1035 nm, is assessed by a modified Bellini-Hänsch interferometer. Mutual spectral phase stability is studied and quantified as a…
