Sentence examples for frequency centroid from inspiring English sources

Seo et al. [13] first divided the audio spectrum (300 ∼ 5,300 Hz) into 16 critical bands, then calculated a normalized frequency centroid for each critical band and used the 16 frequency centroids as the fingerprint of an audio frame.

It represents the same information that has been described in the above point but changing  mm with  mm. Figure 7 Central Frequency, Centroid Frequency, and Fractional BandWidth operators variance and deviation from the theoretical result.

The frequency centroid was computed for each extracted segment using the spectral moment function in PRAAT (v. 5.1.2, Boersma & Weenink, http://www.praat.org/).

Manipulation of/s/acoustics involved a change in the first spectral moment (or frequency centroid): a measure of central tendency in the spectral domain, computed as the amplitude-weighted mean of the frequency spectrum obtained by discrete Fourier transform.

In general, there are two methods to access motor capacity in worms: body bending frequency and centroid velocity [25] [28].

All the 16 candidate VF features, except for peak frequency (PF), centroid frequency (CF), spectral flatness measure (SFM), and Hurst index (Hu), showed a high AUC, i.e., > 0.8.

Some frequency-derived parameters have been also tested such as centroid frequency, central frequency, or bandwidth.

This involved multiplying the normalized responses, r i / (n ⋅ r ¯ ), with the squared distances of the respective frequencies from the centroid, summing across frequencies, and taking the square root.

A plot of beamwidth against centroid frequency overlaying the results of a model of frequency-dependence of beamwidth for static circular piston transducers of different sizes has now been added to the manuscript.

The approach in [9] deals with the problem using a radon transform and a CS-based method to achieve motion parameter estimation of moving targets with Doppler spectrum ambiguity and Doppler centroid frequency ambiguity encountered in SAR systems with low pulse repetition frequency (PRF).

Figure 6 figure supplement 1: plots beamwidth against centroid frequency and the results of a physical model of frequency-dependence of beamwidth for static circular piston transducers of different sizes.
