Sentence examples for frequency laws from inspiring English sources

Signals characterized with multiple components having different frequency laws leave distinct features when examined in the time-frequency domain [5].

After the initial reconstruction, the instantaneous frequency laws must be filtered in order to mitigate the possible gaps that may appear at the transitions between estimation windows [17].

Various time-frequency distributions have been used for the analysis of noisy nonstationary signals with different instantaneous frequency laws [11, 12].

On the other hand, the phase-analysis method needs neither iterative algorithm in each window nor filtering for estimated instantaneous frequency laws.

The HAF-based method tracks the instantaneous frequency laws by dividing the range line of the vibrating target in nonoverlapping windows and locally approximating the phase with a polynomial expression.

Instantaneous frequency law.

We further consider that the b-value of the Gutenberg-Richter's magnitude frequency law is location dependent.

Moreover, a time-frequency tracking algorithm based on the high-order ambiguity function (HAF) is employed to reconstruct the instantaneous frequency law of the micro-Doppler [16, 17].

The modulation features are extracted from the instantaneous phase and instantaneous frequency law (IFL) curve which is calculated according to (14) and (17).

Together with the Gutenberg-Richter's magnitude-frequency law with location-dependent b-values, the elaborated model is applied for short-term, intermediate-term and long-term forecasting of baseline seismic activity.

This can be seen in Figure 7, which gives both the signal and its amplitude and frequency modulation laws.
