Examples in Context
- The motion characteristics of the breaker electromagnet were studied by analyzing the vibration signals and the current in the closing coil in terms of the motion time, frequency spectrum, and energy distribution of the wavelet packet frequency band.
- Based on the local characteristics of signals, a local wave method ( LWM ) can be employed to obtain the instantaneous frequency of signals and the Hilbert time frequency spectrum composed of an energy time frequency three dimensional distribution.
- Wavelet packet can choose different points in time 、 frequency points on the time-frequency resolution freely, different modulation signal wavelet packet decomposition has different energy distribution.
