Remark:
The reference level for the relative attenuation a of the TFS 110X is the minimum of the pass band attenuation a
. The minimum of the pass band

attenuation a
is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at the 30 dB
