2. Characteristics
Remark:
Reference level for the relative attenuation arel of the TFD 65 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 frequency 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.
