Characteristics
Remark: Reference level for the relative attenuation
arel
of the
TFS 110 C
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 (reference) frequency
fc
is the arithmetic mean value of the upper and
lower frequencies at the
3 dB
filter attenuation level relative to the insertion loss
ae
.
