A method (300), system (200), and device (230) for diagnosing an anomaly of a monitored component in a drive train (110), the method including: obtaining original data based on samples of a tachometer signal (305); processing the original data to obtain rotational information (308); processing the original data to produce a sine spectrum (310); determining complex magnitudes of the sine spectrum (310); removing dominate torsional mode residuals from the complex magnitudes of the sine spectrum to produce a frequency spectrum (330); and determining a condition indicator from the frequency spectrum (340).
