Having in mind that this signal was acquired in Spain the
fundamental frequency is expected to be 50 Hz, estimation by the proposed methodology solved it as 50.0209 Hz.
Finally use [[tau].sub.0] to calculate the instantaneous frequency to(t), and get the
fundamental frequency F0 by (23), (24), and (25):
The
fundamental frequency of concrete beams was 37.3 Hz.
It is found that the energy of the signal concentrates around the 10x
fundamental frequency, which is close to the peak at the 2[f.sub.i] + f frequency in the spectral diagram.
the modal analysis provide
fundamental frequency which has already been discussed and helps in providing serviceability criteria for bridges.
They do need to accurately determine the
fundamental frequency so that the voltage and current RMS values can be calculated.
Standard deviation of
fundamental frequency (SD F0) can be taken as an indicator of regularity of pitch of voice.
Figure 9 shows the predicted coherence at the
fundamental frequency. It is presented that the distributions of the coherence predicted with the original width are in good agreement with those with the double width.
The integer multiple of
fundamental frequency is called harmonic which is 50 Hz in our case.
The
fundamental frequency of joists and girders became a focus in Dolan et al.
Therefore, there is the need to identify the
fundamental frequency and the intensity, the energy spectrum, LPC (Linear Predicting Code), the formants, signal-to-noise ratio (S/N), the signal spectrogram, time percentage of the presence of the voice inside the recording and the gender, required in the analysis of the behavior of the voice, which give the proper characteristics of each speaker.
