AM Rejection
AMR Vin = 10mVrms, Note 2
– 40 – dB
Note 1. The input limiting threshold is the FM input voltage for a recovered audio output which is 3dB
less than the recovered audio for an FM input voltage of 200mVrms.
Note 2. The amplitude modulation rejection is determined by:
AMRdB = 20 log Vout for 100% FM Vin / Vout for 30% AM Vin
