Abstract
Method for reducing undesired alarms in an electronic article surveillance (EAS) system involves measuring a tag response at a first and second pedestal to obtain contemporaneous first and second tag responses. The tag responses are compared to evaluate relative signal strength and thereby discern a lesser signal strength tag response. A reduced level exciter drive signal is applied to a selected one of the first and second pedestals associated with the lesser signal strength tag response. A. detection zone is then monitored to determine the occurrence of a third tag response resulting from the reduced level exciter signal. The approximate location of the tag in relation to the first and second pedestals is determined based on the first second and third tag responses.
