The initial two-tone

fundamental frequencies are set as 1.50 and 1.52 GHz, and lower 2HD (3.00 GHz) and IM3 (1.48 GHz) are injected into the input port of STWT.

Comparing the spectrums of a rotor system with pedestal looseness in the literature [3, 4], the spectrum not only contains the

fundamental frequencies of inner and outer rotor, 1/2 fractional harmonic components, but also contains sum frequency and difference frequency of two rotors'

fundamental frequencies, and superharmonic frequencies (such as 2X, 3X, and 4X) are presented.

As seen in Table 2, all configurations have

fundamental frequencies greater than the 15-Hz limit criterion for annoying vibration as proposed by Dolan et al.

As it can be seen, the

fundamental frequencies show that there is an excellent agreement among the results obtained by the two different numerical procedures.

With reference to Figure 9, all modelling concepts have decreasing

fundamental frequencies as the number of storey increases.

For soil-structure resonance assessment we decided to consider larger building stock from different Slovenian towns in which microtremor measurements were conducted recently to derive the range of

fundamental frequencies for comparison, because the building typology is similar in wider area.

The YIGs are provided up through Ku-Band, and these

fundamental frequencies also minimize spurious signals in advanced radars.

The output amplitude at the

fundamental frequencies is(4)

To find the pitch range of a word, we repeated the procedure as noted earlier, except that the frequency difference between the syllables with the highest and lowest

fundamental frequencies was calculated.

The aerodynamic turbulence of the glottic air leak is perceived as "breathiness." Voice may also have a bitonality or diplophonia, with the perception of two different

fundamental frequencies (or pitches) simultaneously.

NIST researchers have made the first spectral measurements of a directly coupled array and found that harmonic distortion was more than 80 dB below the amplitude of synthesized

fundamental frequencies of I kHz and 50 kHz.

He excites one note electromagnetically at one of its

fundamental frequencies, then uses the interferometer to visualize which areas of the playing surface reverberate.
