Abstract

Una disposición para vigilancia electrónica de artículos y método para llevar a cabo una vigilancia electrónica de artículos, donde una senal recibidaen una disposición de vigilancia electrónica de artículos es filtrada en un modo peine pararemover la interferencia. Una segunda función de filtrado peinees provista para detectar situaciones cuando el primer filtrado peine genera interferencias de oscilación respuesta a los ruidos de impulsos. Lasindicaciones de alarma son inhibidas cuando las interferencias debido a ruidos de impulsos son detectadas. Los anchos de bandas de las funciones de filtradoson ajustables en respuesta a la entrada hecha por el operador
