A novel threshold segmentation instantaneous frequency calculation approach for fault diagnosis

A novel threshold segmentation instantaneous frequency calculation approach for fault diagnosis

Instantaneous frequency can well track and reflect the transient information of signal, so it plays an important role in the analysis and processing of the non-stationary signal. In this paper, the single component signal is compared with the Second Order Differential Equation in polar coordinates....
