Fault Detection During Power Swings Using the Properties of Fundamental Frequency Phasors

IEEE Transactions on Smart Grid, 2019
Among short-circuit faults, those occurring during power swings are more harmful to power system stability and thus, they should be detected quickly and reliably.

Encoding voice fundamental frequency into vibrotactile frequency

The Journal of the Acoustical Society of America, 1979
Measured in this study was the ability of eight hearing and five deaf subjects to identify the stress pattern in a short sentence from the variation in voice fundamental frequency (F0), when presented aurally (for hearing subjects) and when transformed into vibrotactile pulse frequency.

The perception of fundamental frequency declination

The Journal of the Acoustical Society of America, 1979
A series of experiments was carried out to investigate how fundamental frequency declination is perceived by speakers of English. Using linear predictor coded speech, nonsense sentences were constructed in which fundamental frequency on the last stressed syllable had been systematically varied.

Redefinition of Fundamental Frequency

The Journal of the Acoustical Society of America, 1962
Fundamental frequency of normal and esophageal utterances was measured by (1) number of pulses in a spectrographic continuous-amplitude display, (2) number of cycles in an oscillographic wavetracing, (3) harmonic interval in a narrow-band spectrogram. The results obtained by these measures yield widely varying fundamental frequencies.

Time and frequency in fundamental metrology

Proceedings of the IEEE, 1991
The author shows that because time and frequency are the most accurately measured physical quantities, it is desirable to tie other physical quantities to time and frequency measurements. A review of the progress that has been made in this direction along with speculation on possibilities for the future are given.

Frequency Code: Orofacial Correlates of Fundamental Frequency

Phonetica, 1987
Abstract In the human voice, lip retraction as in smiling can be associated with high fundamental (F₀) and formant frequencies. The aim of this study was to investigate under naturalistic conditions the cross-species generality of the frequency code hypothesis and related orofacial correlates in F₀.

Fundamental Frequency Estimation

1976
The fundamental frequency (F0) is a basic parameter in acoustical studies of speech. It is also a necessary parameter for low bit rate speech coding systems. It is generally considered to be one of the acoustical correlates to the perceived intonation pattern of speech.
