Remark:  
The reference level for the relative attenuation a of the TFS 121B is the minimum of the pass band attenuation a  
. The minimum of the pass band  
min  
rel  
attenuation a  
is defined as the insertion loss a . The centre frequency f is the arithmetic mean value of the upper and lower frequencies at the dB  
min  
e c  
filter attenuation level relative to the insertion loss a . The nominal frequency f is fixed at 121,5 MHz without any tolerance. The given values for both the  
relative attenuation a and the group delay ripple have to be achieved at the frequencies given below even if the centre frequency f is shifted due to the  
temperature coefficient of frequency TC in the operating temperature range and due to a production tolerance for the centre frequency f .
