Brown, February 9, 1995 Typically the attenuation is defined in decibels, and fixed attenuators may be available in a variety of levels. reversed polarity. A is the attenuation in dB. Cutoff frequency (also known as corner frequency, or break frequency) is defined as a boundary in a system’s frequency response at which energy flowing through the system begins to be attenuated (reflected or reduced) rather than passing through. R ' = ( Z1 - Z2 )/(Z1 + Z2 ) A 0 = R = ( Z2 - Z1 )/( Z2 + Z1 )First Interface Reflection, Buffer-Specimen This typically is measured in decibels (dB) or voltage and can occur due to a variety of factors. B0B2 = [(R e (exp) -a2L ) R e (exp) -a2L] / (1- R²) = How to use attenuation in a sentence. a = nepers per unit length T ' = ( Z1 - Z2 )/(Z1 + Z2 ) + 1 There's a bit of a twist with attenuation, it increases with frequency; the higher the frequency the higher the attenuation.
