Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 112 is the minimum of the passband attenuation amin. The minimum of the passband
attenuation amin is defined as the insertion loss ae.The reference frequency fc is the arithmetic mean value of the upper and lower frequencies at
the 30 dB filter attenuation level relative to the insertion loss ae.
