The Spectral Coherence Function – Cyclostationary Signal

WebCyclostationarity of vibration signals from the bucket wheel excavator has been also investigated in [17] where a Spectral Coherence Map is proposed as a tool for fault detection. A comprehensive discussion on modeling of vibration signal from gears and bearings can be found in [18]. WebCorrelation/Coherence (OO-CSC and OO-CSCoh) has been proposed [3]. The method has shown a robust detection of the hidden modulations under carrier of random frequency. shannon lied 1983WebFeb 15, 2024 · Signals of first order of cyclostationarity (CS1) are signals whose first-order statistical moment is a periodic function of T that complies with the condition of Eq. 1: (1) C 1 x ( t) = E { x ( t) } = C 1 x ( t + T) where E denotes the ensemble averaging operator, t stands for time and T stands for the period. shannon l hall attorney
