The resonant mode is determined by comparing the signal applied to the resonator as delivered by the PZTs to the signal measured by the hydrophone. The initial part of this work presents a qualitative analysis of the acoustic system. The idea is to gain knowledge about the system frequency ...

In the immediate vicinity of the resonant frequency ω0 , the transmission coefficient varies sharply from 0% to 100%. From Eq. (5), one can determine that the transmission vanishes at a frequency ωr=ω0 , w 为谐振频率多数选择,另一方面,光谱显示分明不对称的线形。 在谐振频率ω0的临近...
1 on the frequency response curve (FRC) of a hardening Duffing oscillator. The solid and dashed arrows depict that the amplitude of the response changes in a different way when the frequency is increased or decreased. Sudden changes of the amplitude occur from Point A to Point B (this ...
When the Injection current frequency within a range, you can change a corresponding impedance - frequency harmonics of the distribution curve, in the diagram, the valleys and peaks can be determined that the node that string, and the resonant frequency. ...
Switching frequency of ac-dc stage (50kHz to 150kHz) and resonant frequency of dc-dc stage (50kHz to 350kHz) Values of passive components Inductor, transformer and capacitor design By working through all possible design variants, a range of results were attained that, when combined with ...
The polarized CARS spectra are recorded at a series of polarization angles Ф_d, and simulated by a Lorentz bandshape to obtain signal amplitude H_R of the resonant part. From the dependence of H_R on polarization angleФ_d, the angleФ_d~0 corresponding to H_R=0 can be determined. ...
the VFD based on frequency lockout bands to avoid excessive vibration and noise within a desired speed range due to resonant frequencies. The test system further comprises one or more predetermined vibration sensors installed at predetermined locations within the product. The controller/computer is ...
We determined that the Chevreul pendulum illusion is produced when the fingers holding the pendulum generate an oscillating frequency close to the resonant frequency of the pendulum. At an appropriate frequency, very small driving movements of the arm are sufficient to produce relatively large pendulum...
In the design of any RFID tag, there are often requirements to optimize the resonant frequency according to the RFID reader circuit. The radio frequency resonance is based on the fundamental equations for an LRC (inductor-resistor-capacitor) circuit. For an LRC circuit, the resonant frequency is...
