ABSTRACT:
A signal received in an electronic article surveillance system is comb-filtered to remove interference. A second comb-filtering function is provided to detect occasions when the first comb-filtering generates ringing artifacts in response to impulsive noise. Alarm indications are inhibited at times when the artifacts due to impulsive noise are detected. Bandwidths of the filtering functions are adjustable in response to operator input.
