Remark:
Reference level for the relative attenuation arel and the band width BW of the TFS 71 D is the minimum of the pass band
attenuation amin. The minimum of the pass band attenuation amin is defined as the insertion loss ae. The center frequency fo
is the arithmetic mean value of the upper and lower frequencies at the 1,5 dB filter attenuation level relative to the insertion loss
ae.
