attenuation factor การใช้

• Most oscilloscopes allow for probe attenuation factors, displaying the effective sensitivity at the probe tip.
• Q is the anelastic attenuation factor or the seismic quality factor, a measure of the energy loss as the seismic wave moves.
• The lake basin analysis uses the volume of the lake and pollutant-specific attenuation factors to calculate a population of average-annual lake concentrations.
• For lower frequencies, the attenuation factors are much lower, the achievable heating depths are higher, and the temperature gradient within the tissue is lower.
• :: We're talking about'Q'anelastic attenuation factor ( or strictly its inverse ), the degree to which rocks absorb seismic energy.
• Eyewear is rated for optical density ( OD ), which is the base-10 logarithm of the attenuation factor by which the optical filter reduces beam power.
• This results in a . 1 (  10X ) attenuation factor, but helps to isolate the capacitive load presented by the probe cable from the signal being measured.
• Since this cross-correlation is equal ( save for the K attenuation factor ), to the autocorrelation function of \ scriptstyle s _ { c'}, this is what we consider:
• In the case of non-birefringent materials, however, the 2? Jones matrix is the identity matrix ( multiplied by a scalar phase factor and attenuation factor ), implying no change in polarization during propagation.
• A superconductive Faraday cage would probably exclude the magnetic field right down to DC ( see the Meissner effect ), but non-superconductors must have a practical lower limit ( combined with an attenuation factor ).
• Some probe designs have additional pins surrounding the BNC or use a more complex connector than a BNC . These extra connections allow the probe to inform the oscilloscope of its attenuation factor ( 10? 100? other ).
• The two polarizations are mutually discriminated by a cross-polar-discrimination factor ( XPD, for more details see XPIC ) : at the receiving site, XPD is the attenuation factor of each polarized stream towards the cross-polarized one.
• Both the surface and atmospheric weights are dependent on the surface emissivity e _ S, the absorption coefficient \ kappa ( z ) and the earth incidence angle \ theta; the surface weight is the product of e _ S and an attenuation factor:
• In particular, if the frequencies are correct, but the phase is wrong, contribution from \ theta is a constant attenuation factor, also \ Delta \ omega \ cdot t represents a cyclic inversion of the recovered signal, which is a serious form of distortion.
• In this equation a _ 1 and a _ 2 are attenuation factors, E _ y is the luminance signal, ( E _ b-E _ y ) and ( E _ r-E _ y ) are the so-called color difference signals and \ omega is the angular frequency of the color carrier . \ omega is within the luminance bandwidth.
• Then from the first surface the maximum contribution is 0.5, for the reflection from the second : 0.5 * 0.5 = 0.25, the third : 0.25 * 0.5 = 0.125, the fourth : 0.125 * 0.5 = 0.0625, the fifth : 0.0625 * 0.5 = 0.03125, etc . In addition we might implement a distance attenuation factor such as 1 / D2, which would also decrease the intensity contribution.
