All three systems were able to achieve tuning within their operating regime when driven at a single frequency, as well as maintain a tuned condition as frequency was stepped up or down, demonstrating a bandwidth between 6 and 40 Hz.
Overdetermined, least-mean-squares calculations are used to minimize model error throughout a frequency band rather than at a single frequency as in the corresponding linear estimators.
Previously, scientists hadn't discovered fossils that preserved the music-making structures, so they couldn't determine whether the ancient insects chirped at a single frequency, as some living species do, or across a variety of frequencies.
Narrow-banded processes dominated by a single frequency, as well as bimodal processes with two dominating frequencies in the structural response are considered, and all results are compared with those of numerical simulation.
The numerical estimations outlined in the preceding section focus on a persistent seismic wave with a single frequency as a source of the piezomagnetic effect: temporal variations in seismic waves are ignored.
A differentiating feature of a CPVA is that it is tuned not to a single frequency (as are traditional frequency tuned dampers), but rather to a multiple of average rotation speed, or order.
First, wideband LFM signal was represented as a sine wave with a single frequency in FrFT domain, so that the time-invariant steering vector can be obtained for the original SPICE algorithm.
For example, in the FA power spectrums of Figure 1, each component had a broad Gaussian-like distribution (i.e., suggestive of a band of frequencies) rather than a sharp peak (i.e., suggestive of a single frequency) as it would be the case for a pure sinusoid.
As the harmonic motion consists of a single frequency, the study of the structure with TLD will provide an understanding of the behaviour of TLD-structure system for this kind of motion.
The method involves monitoring the response of the guillotined electrode to a single frequency perturbation continuously as a function of time.
The frequency generator is set to a single frequency, and the user experiences this as an audible, single-pitched tone.
