Sentence examples for maximum frequency error from inspiring English sources

This significantly reduced the maximum frequency error to only 4%.

It should be pointed out that regardless of the adopted window type and the value of λ 0, the maximum frequency error of the new algorithm never goes above 10−3, even though only one or two cycles are obtained.

They established a rule to optimize the decision process, using the p-value introduced by Fisher, by setting the maximum frequency of errors that would be admissible.

The maximum absolute frequency errors |δ|max are shown in Figs. 9 and 10 as a function of λ 0 for the two-term and three-term MSD windows, respectively.

The second frequency offset was chosen to be larger than the maximum frequency offset estimation error of the frequency synchronisation algorithm.

The relative root mean square (RRMS) error of the maximum frequency extracted from the AD-PCNN spectrogram of the simulated Doppler blood flow signals is decreased 25.2% on average compared to that extracted from the MPWD (matching pursuit with Wigner Distribution) spectrogram, and the RRMS error of the AD-PCNN spectrogram is decreased 10.8% on average compared to MPWD spectrogram.

Table 1 The mean and standard deviation of the RRMS errors of the maximum frequency waveforms extracted from the signals with different SNR levels based on the STFT, the MPWD methods, and the AD-PCNN methods (×10-3).

From Table 1 it can be concluded that the RRMS errors of the maximum frequency waveforms extracted from the PCNN spectrograms have decreased much more than those before noise and speckle reduction.

For example, the RRMS errors of the maximum frequency waveforms of the original STFT are 2.92 and 3.84 times higher than those denoised by using MPWD and AD-PCNN on Doppler signals with SNR = 10 dB, respectively.

It is found that in all cases, the RRMS errors of the maximum frequency waveforms and the spectrograms based on the AD-PCNN method are smaller than those based on the STFT and MPWD, which means that the AD-PCNN spectrograms are much closer to the theoretical ones and contain least extra frequency components and least distortion in the estimated maximum waveforms.

While the MPWD has presented the RRMS errors of the maximum frequency waveforms,, and results on Doppler signals with SNR = 0 dB, 5 dB, 10 dB, and, respectively, the AD-PCNN has presented the RRMS errors 9.68%, 38.10%, 31.58%, and 21.43% decrease compared to MPWD spectra.
