A Vibration Feature Extraction Method Based on Time-Domain Dimensional Parameters and Mahalanobis Distance
To accurately describe the characteristics of a signal, the feature parameters in time domain and frequency domain are usually extracted for characterization. However, the total number of feature parameters in time domain and frequency domain exceeds twenty, and all of the feature parameters are use...
