Related to Fundamental frequencies: fundamental wavelength

fun·da·men·tal fre·quen·cy

the principal component of a sound, which has the greatest wavelength, hence the lowest tone in a sound; sounds are composed of a fundamental tone and overtones or higher tones. See: harmony, noise.

fun·da·men·tal fre·quen·cy

(F0) (fŭn'dă-men'tăl frē'kwĕn-sē)
1. acoustics The basic frequency of a vibrating object or sound as opposed to its harmonics, or the principal component of a complex sound wave.
2. The frequency of vocal fold vibration at the glottis, unaffected by resonance.

The spectrums of vibration displacement of inner and outer rotor not only contain the sum frequency and difference frequency of two rotors' fundamental frequencies but also contain some superharmonic components (such as 2X and 3X), and, especially for the loose rotor, the multiple harmonic components are more prominent.
These fundamental frequencies represent an assumption that no composite action between the subflooring and joists exists as a result of the small effective flange widths determined in the previous research (Dolan et al.
The UTEP scientists discovered that the harmonics resonated more strongly than the fundamental frequencies, which might contribute to the pan's unusual sound.
The IDT M675S02 series is a single-frequency, single-output VCSO for low-jitter and low-phase noise clock generation, supporting fundamental frequencies from 500 MHz to 1 GHz.
The push-push oscillator circuit configuration enhances the second harmonic and suppresses the fundamental frequency output, doubling the fundamental frequencies so that higher operating frequencies can be obtained, beyond the limitation caused by the cut-off frequency of available three-terminal active devices.
The fundamental frequencies of individual and salvaged joists differed by about 15 percent (Table 5) due to differences in beam stiffness as previously reported (2).
She measured the fundamental frequencies of nine men and women, most of them college students in San Diego, and then tested their perception of the tritone paradox.
5] octave (high for males and medium for females), where fundamental frequencies are between 261 Hz and 523 Hz, the second harmonic varies from 523-1047 Hz.
The new VTOs operate at fundamental frequencies with no inherent spurious responses or subharmonics.
The predicted fundamental frequencies of joists in the 88 Johnson [5] floors were calculated using Equation [2].
