The three phase detecting method closely connects with the Park transform and the result is the positive sequence part of the fundamental frequency.
The frequency associated with the first mode is sometimes called the fundamental frequency.
The filter has no fundamental frequency decay and phase delay, and all harmonics above2nd order are filtered.
It is shown that the offset of propulsion force and the lower natural fundamental frequency are caused by asymmetry of turbopump and weakness of connection stiffness between propulsion and frame.
The Chinese tones take great effect on the quality of synthesis speech. Analysing the variations of fundamental frequency, the length of tone and the intensity...
The duration and fundamental frequency can be changed by adjusted the speech parameters.
The experimental items include the fundamental frequency (Fo), the rimal duration, the amplitude and the formants.
Got some rules can not be observed in the frequency spectrum: there are some line spectrums that have a certain relationship with the fundamental frequency.
The numerical results indicate that the higher-order mass matrices have a negligible influence on the fundamental frequency, but they affect the frequencies of higher mode vibrations considerably.
The relation of the impedance of fundamental frequency and the firing angle is the key factor in firing control of TCSC.
