Abstract
Comprende una pluralidad de circuitos LC (1) en escalera cuya respuesta está determinada por una banda de paso (fpi, fps) y una banda de rechazo (0 a fri y frs a infinito); se caracteriza porque en paralelo con la carga del filtro se disponen en serie dos circuitos tanque (5), cuyas frecuencias de resonancia coinciden con la frecuencia de corte inferior (fpi) y superior (fPs) de la banda de paso del filtro. Además comprende una resistencia de control (Rc) que regula el efecto de los circuitos tanque sobre el filtro. Esta estructura permite compensar el efecto de las limitaciones reales de los componentes LC (1) para ajustar la respuesta del filtro paso banda analógico creado con estos componentes a la respuesta del filtro paso banda ideal.
