Rundfunkempfänger

摘要

This invention relates to a receiver which receives angle-modulated radio signals and includes a means to detect occurrence of interference from adjacent channels when an envelope of demodulated signal of the received radio signals exceeds a threshold (73). This invention intends to improve the quality of received signals by such processing as to block off (4) the received signals, to attenuate them, to limit the amplitude thereof, or to block them and to insert interpolation signals in replacement thereof when the detection output is transmitted from the above circuit. The interference detection circuit can also be employed in diversity receivers to improve the selection of an undisturbed channel.
