The phrase "attenuation over" is correct and usable in written English.
It can be used in contexts related to signal processing, telecommunications, or physics, where it describes the reduction in strength of a signal as it travels over a distance or through a medium.
Example: "The attenuation over long distances can significantly impact the quality of the transmitted signal."
Alternatives: "reduction in" or "loss of".
In the development of dipole active attenuators it has been shown that the "Chelsea dipole" can give attenuation over a wide band.
One of these vectors is based on the highly attenuated modified vaccinia virus Ankara (MVA) that was originally obtained by attenuation over more than 500 passages in chicken embryo fibroblast cultures [1], [2].
Moller, I. et al. Wave attenuation over coastal salt marshes under storm surge conditions.
Absorbing low-reflectance black materials reduce the SNR but the effect is minor compared with the squared attenuation over distances.
Results: A persistent zone of high attenuation over 6 months suggested the high possibility of recurrence.
Conversely, amplitude attenuation over similar sensor spacing is strong, yielding greater potential model sensitivity.
The linear regression revealed that, for E. coli, in-home attenuation increased over time less than natural attenuation, 0.25 logs/day (p = 0.01).
The main objective was to achieve target impedance at the front absorber face, so as to attain maximum sound-attenuation over a wide frequency bandwidth.
Figure 7 shows comparison between the measured and predicted attenuations over the terrestrial links at equiprobable exceedance probability (0.001%≤%p≤1.0%).
Since, as stated above, we have assumed the same statistics for the marginal attenuations over each path, Equation (27) simplifies to r = e c d σ 2 - 1 e σ 2 - 1. (30).
Using the power-law relationship for the attenuations over the link segments, the measurement model can be constructed in the following way, y_{i,t} = a_{i,t}sum_{j=1}^{N} u_{j,t}^{b_{i,t}}l_{ij} + e_{i,t},quad i=1,dots,M, (1).
