Abstract
A method and circuit for suppressing periodic noise interference in a broadcast signal received by a receiver, in which, during reception of the broadcast signal a dip occurs in the amplitude of the received broadcast signal each time noise interference is present, each dip having a slope, by the steps of: determining the values of the amplitude of the received signal; setting a basic received signal threshold value which is less than the value of the received signal at a time when no noise interference is present; during each occurrence of noise interference, increasing the threshold value by an amount proportional to the slope of the corresponding dip in the amplitude of the received signal; and acting on the received signal to suppress noise interference during a time when the amplitude of the received signal is below the increased threshold value produced by the increasing step.
