Abstract
The disclosure relates to an automatic search tuner in which an erroneous stop of an automatic search operation can be prevented by an interference signal generated due to an intermodulation interference. The automatic search tuner comprises an attenuating means for attenuating the level of a received signal in a predetermined amount in response to a signal indicative of stopping an automatic search operation; and a comparing means for comparing the level of a signal obtained when the attenuating means is operating with the level of a signal obtained when the attenuating means is not operating. An automatic search operation is resumed by the signal outputted from the comparing means.
