Sentence examples for instantaneous spectrum from inspiring English sources

The measured time-resolved spectra of the beat signal illustrate that the beat signal suffers from both frequency drift and instantaneous spectrum broadening, which indicates that the wavelengths of the lightwaves experience drift and jitter.

This monomer concentration is established with the use of its UV-visible absorbance in the vicinity of the monomer band(s) during this process on the basis of an original procedure to separate the absorbances due to the monomer and solute oxidation products for each instantaneous spectrum.

Whitening is then achieved by normalizing the instantaneous spectrum with this estimated noise spectrum.

However, the actual sparsity s is often unknown since it corresponds to the instantaneous spectrum occupancy of PUs which is dynamically varying.

Here, the IB refers to the bandwidth of instantaneous spectrum at every time instant when the energy density of the respective component drops by 50% from its maximum.

In this paper, we apply the Hermite projection method to time-frequency regions by expanding each row (i.e., the instantaneous spectrum) into a series of Hermite functions.

The instantaneous spectra of the FH interferers are then estimated using a sparsity-based approach that takes the inherent properties of FH signals into account.

Respiratory signals from TTSR are non-stationary and relatively narrow band, while xR t) from TTCR are characterized by a wider instantaneous spectra.

The spectral subtraction filter uses the instantaneous spectra of the noisy signal and the running average (time-averaged spectra) of the noise, whereas the Wiener filter is based on the ensemble average spectra of the signal and noise.

The CPSD is smoothed to avoid the jumps and variations seen on the instantaneous spectra through a first-order IIR filter given by1 overline{S}_{e_{l},e_{j}}(mu,k) = alpha_{mathrm{E}},tilde S_{e_{l},e_{j}}(mu,k) + (1 - alpha_{mathrm{E}}),overline{S}_{e_{l},e_{j}}(mu,k-1), (18).
