Characteristics
Remark:
Reference level for the relative attenuation arel of the TFS 433 F 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 fo is the arithmetic mean
value of the upper and lower frequencies at the 3 dB filter attenuation level relative to the insertion loss ae.
