Sentence examples for instability in the frequency from inspiring English sources

A second effect of articulatory tremor that can be measured in the acoustic signal is the instability in the frequency response of the vocal tract.

A second effect of articulatory tremor, illustrated in Figure 11, is the instability in the frequency response of the vocal tract.

Another specific feature of articulatory tremor that can help in differentiating it from respiratory tremor is the instability induced in the frequency response of the vocal tract.

Numerical simulation shows that Parker instability in the high frequency domain (wave number m > 20) may accelerate magnetic fibrils to emerge into the solar atmosphere at supersonic speed.

It was found that the stability condition for the NAF control is static and it can effectively increase the damping of the target natural mode without causing instability in the low frequency region.

In this case, however, due to the variation of the laser tube temperature around the temperature 23 °C, the length of the laser tube may alter, which in turn causes the movement of longitudinal modes on the gain profile of the laser and, consequently, an instability in the laser frequency.

To avoid instability in the regression analyses, frequency distributions for categorical predictors will be examined and categories with small numbers of respondents will be combined.

The effect of the delay and phase instability of the frequency standard in the satellite is cancelled in Eq. (12b).

When the return signal is mixed with the local frequency standard a phase can be obtained as (7) where the phase variation caused by the instability of the frequency standard in the satellite is included in (the phase variation of is very small compared with ), and is the delay from the frequency standard to the mixer in the satellite.

Equation (12b) suggests that the delay changes and phase instability of the frequency standard in the satellite do not directly affect the phase difference of the signals from the two landers.

The signal which returns directly from the antenna in the satellite is named the return signal and reaches the mixer after a delay The phase of the return signal in the satellite at the input of the mixer is expressed as (6) where is the phase variation of the carrier signal and is caused by the instability of the frequency standard in the satellite.
