It has both excellent high frequency and low frequency characteristics.
The excellent low frequency characteristics show the potential applications of this material in piezoelectric generators harvesting environmental vibration energy.
Impedance characteristics for three frequency regions were studied bulk solution-influenced high frequency response, medium frequency parameters representing adsorption of surface active lubricant additives at the electrode interface, and low frequency characteristics related to diffusion and charge transfer processes.
Here we have shown its application in a broad range of physiological signals including epileptic seizure data, EEG data with very low frequency characteristics, MEG data and evoked response recordings.
Compared with conventional digital filter, low-pass filter based-on CBSRS has the advantage of extracting some certain weak low-frequency characteristic components while implementing low-pass filter.
As is well known, it may be more difficult to detect gear faults at low speed because low-frequency characteristics are easily masked by heavy noise [18].
Availability of low-frequency characteristics of sound insulating elements is required in order to achieve efficient control of noise sources and reduced level of annoyance in the low-frequency range.
The novel hydrophone not only possesses satisfactory directional pattern as well as miniature structure, but also has good low-frequency characteristics, and satisfies the requirements for low-frequency acoustic measurement.
As we can see form Table 7, the governing system has some influence on low frequency oscillation characteristic, but not as large as the excitation system (PSS).
It is considered that normally the governing system has some influence on low frequency oscillation characteristic, but not as large as the excitation system (PSS).
