Characteristics

Remark:

Reference level for the relative attenuation arel of the TFS 1220 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 centre frequency fc is the arithmetic mean value of the upper and lower frequencies
