In order to suppress interference elimination circuit 13 impulse noise in the case of an fm - receiver and method therefor

摘要

entstu00f6rungssystem for suppression of impulsrauschen in an fm receiver, with which a stu00f6rkomponente from an fm demodulationssignal filtered out, the ausgefilterte stu00f6rkomponente with a gain is enhanced by an automatic verstu00e4rkungsfaktorsteue rsignal depending on a level of enhanced stu00f6rkomponente is controlledand a control signal is provided for - which is triggered when the level of enhanced stu00f6rkomponente is higher than a predetermined level and the control signal to the interruption of the transmission from the fm demodulationssignals at a subsequent stage is interrupted, so that egg n in the fm demodulationssignal contained impulsrauschen is suppressed.it is the predetermined value, in which the out of - control signal trigger is changed depending on the automatic verstu00e4rkungsfaktorsteuersignal or in dependence on a pegeldemodulationssignal, a level of the received signal.
