The phrase "attenuation setting" is correct and usable in written English.
It can be used in contexts related to audio, signal processing, or any field where the reduction of signal strength is relevant.
Example: "Adjust the attenuation setting to improve the clarity of the audio output."
Alternatives: "signal reduction level" or "damping adjustment".
Control design is a rich problem which requires consideration of many issues such as load disturbance attenuation, set-point tracking, robustness with respect to process variations and model uncertainty, and effects of measurement noise.
The quality factors for P and S wave attenuation were set to be Qs = 300 and Qp = 2Qs, based on the method of Robertsson et al. (1994), within the entire model space.
In our experiments, in order to ensure that the emitting power does not vary during the transmissions, the signal attenuation is set to a certain constant value (45 dB).
Matrix attenuation was set at 2,500Da and shot sequence was set with one warming shot at 2000 (nJ) followed by 4 data shot at 1800 (nJ).
The detector attenuation was set to 1000 Da and masses up to 200,000 Da were detected with a focus at 8000 Da.
The filter gains are optimized in the sense of noise attenuation level of H∞ setting.
As in the HP experiment, CT-based streak artifacts and background noise were removed by setting all attenuation coefficients in the scaled CT image below μ=0.001 mm−1 to zero.
The area was measured with commercially available CT software (Rapidia 2.8; INFINITT, Seoul, Korea), which electronically determined the adipose tissue area by setting the attenuation values for a region of interest within a range of −250 to −50 Housefield units.
Attenuation coefficients were based on a relative scale by setting the lowest calculated attenuation value for the specimens (a fibroadenoma) to 0.003 Nepers/cm.
As the scattering is now accounted for, the attenuation coefficient μ in Equation 1 is now the total attenuation coefficient and was set to the water attenuation coefficient at the middle of the energy acquisition window (μ = 0.17 cm-1), both in the scatter modeling procedure and in the phantom pinhole SPECT reconstruction.
