Abstract
A detector for indicating reception disturbances during frequency modulated ultrashort wave broadcast reception, particularly in power vehicles, has a detector for indicating frequency disturbance deviations in high frequency or intermediate frequency carriers and an amplitude modulation detector for indicating disturbance amplitude modulation in the high frequency or intermediate frequency carrier, and an evaluating circuit with two inputs arranged so that the output signals of the detectors are supplied to the respective inputs of the evaluating circuit and an output signal of the evaluating circuit depends both on the disturbance amplitude modulation and the frequency disturbance deviation.
