2. Characteristics

Remark:

Reference level for the relative attenuation arel of the TFS 75 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 reference frequence fc is the arithmetic mean value of the upper and lower

frequencies at the 20 dB filter attenuation level relative to the insertion loss ae.
