Sentence examples for frequency variances from inspiring English sources

'Praat' was used to quantify the fundamental frequency variances in the conditions melodic intoning and rhythmic speech separately for each lyric type.

These were used to determine the range of allele frequency variances that matched the frequency variance under selection at the corresponding t nearlyfixed.

V a r (d j | T N E T ′ ) and V a r (d j | T R a n d o m ′ ) refer to document frequency variances of d j in T N E T ′ and in T R a n d o m ′.

The design variable tolerance effects on the natural frequency variance of constrained multi-body systems in dynamic equilibrium are investigated in this study.

However, in practical applications, the accuracy of harmonic estimation would be reduced under some situations, especially in cases of fundamental frequency variance and background noise presence.

In the other proposed approach, the sum of the time variance and frequency variance is used to formulate a positive definite matrix to measure the time frequency joint localization of a bandlimited function from its samples.

In this paper, we compute the frequency variance of the filter from its discrete Fourier transform (DFT) and propose an equivalent summation based discrete-time uncertainty principle which has the lower bound of one.

For a chosen frequency variance, we formulate the search for "maximally compact sequences" as an exactly and efficiently solved convex optimization problem, thus providing a sharp uncertainty principle for sequences.

Gabor's uncertainty principle states that a function cannot be localized in time and frequency domain simultaneously and there exists a nonzero lower bound of 0.25 on the product of its time variance and frequency variance called time frequency product (TFP).

We propose a design method for time frequency localized three-band biorthogonal linear phase (BOLP) wavelet perfect reconstruction filter bank (PRFB) wherein the free parameters can be optimized for time frequency localization of the synthesis basis functions for the specified frequency variance of the analysis scaling function.

which shows that the frequency variance is determined by the parameters of the signal and the window in the first term, the square of mean frequency in the second term, and the scaled square of the estimation error of the polynomial parameter ω1 in the last term.
