Characteristics

Remark:

The reference level for the relative attenuation arel of TFS 111B is the minimum of the pass band attenuation amin. This value is defined as the

insertion loss ae. The centre frequency fc is the arithmetic mean value of the upper and lower frequencies at the 20,0 dB filter attenuation level

relative to the insertion loss ae.
