Verfahren zur Überprüfung der von einem Nachbarsensor beeinflussten ZF-Bandbreitensteuerung eines Hörrundfunkempfängers

摘要

The method involves sending an amplitude modulated signal with two side bands to the receiver (2) from a measurement transmitter (10), tuning the receiver to one side band and measuring the DC voltage produced by the AM signal carrier in the adjacent channel sensor (4), tuning to the other side band and measuring the DC voltage, tuning to the unmodulated carrier and measuring the DC voltage and evaluating the measured DC voltages.
