Sentence examples for at higher order frequencies from inspiring English sources

Results show that the Timoshenko beam theory is necessary at higher order frequencies due to the error caused by other theories like Euler Bernoulli, shear or Rayleigh beams.

Because the instrument also transmitted ions at higher order frequencies (harmonics), the technique was termed overtone mobility spectrometry.

This enables one to study the effects of slenderness ratio on the natural frequencies, especially at higher order modes.

However, we observe strong response at high-order intermodulation frequencies which is not included in the theory.

Increases in pipe wall response and external radiation are largest at frequencies at which higher order acoustic modes can propagate, in which case coincidence effects lead to strong excitation of supersonic pipe modes.

Conventional element-based methods, such as the finite element method (FEM) and boundary element method (BEM), require mesh refinements at higher frequencies in order to converge.

The pressure and velocity spectra (Agarwal, PhD Thesis, 1985) of the internal sound field show a strong plane wave component at low frequencies and the presence of higher order acoustic modes at the higher frequencies.

At high frequencies of order only 3 points per wavelength are needed, which compares very favorably to boundary integral methods.

As shown on the graph, the results are more accurate at high frequencies than low frequencies.

It is well known that an area discontinuity generates evanescent higher order modes even at low frequencies within the plane wave limit.

Signals were analog filtered at 10 500 Hz (with first order filter at lower cutoff frequency and sixth order filter at higher cutoff frequency), amplified 2000× and sampled at 1 kHz using a TeleMyo 900 telemetric hardware system (Noraxon USA, Inc., Scottsdale, AZ, baseline noise < 1 uV RMS, Common Mode Rejection min. 85 dB through 10 500 Hz operating range).
