Based of Wigner-Ville cross-terms distribution properties of amplitude modulation signals, an approach of cross-terms false spectral energy to diagnose machinery faults was presented firstly, and then the transmission band core function was designed to extract the cross-terms false spectral energy of amplitude modulation signals. Finally, the real life gear data was provided in order to show the availability of the approach.
