N2 - The transfer function between the rotating component and the sensor complicates the diagnosis process. In this study transfer function estimation is considered, based on spectrum background estimation and minimum phase. The ability to suppress peaks that are smeared as result of high instantaneous speed fluctuations is limited, and thus we extend former work for mitigating this challenge. The synchronous properties of the gear signal are used in the cycle domain for separating them from the wideband noise using liftering in the cepstrum domain. The signal is divided to consecutive segments for enabling original phase restoration for converting back the low quefrencies of the noises that correspond to the original spectrum background to the time domain.
