| Abstract: | Based on the features of nonstationary and bandpass signal, the Classen's algorithm for Wigner distribution is improved in this paper, which can avoid the problem of aliasing in discrete calculation. The improved algorithm is easy, and it is adapted for bandpass filtering, moreover its calculating velocity is quite high.,The faults of roll bearing are investigated by 3D-Wigner and 2D-Wigner distribution plot, some advantages are shown in analysing fault characteristics of engineering examples. |
