## Abstract Timeβfrequency and timeβscale transforms are one of the powerful mathematical methods for feature extraction of nonβstationary signals such as partial discharge (PD) signals. Modified Fourierβbased transforms and Wavelet transforms are well known among them. PD signals can be analyzed b
The signature of the vibration generated by a fault on a gear is carried by the sidebands around the dominant tooth meshing harmonic. This paper applies the linear wavelet transform based on B-spline wavelets to reveal the spectrogram of the sidebands exactly. The proposed wavelet transform uses 1/a
