Abstract

Mejoras en dispositivos eléctricos de eliminación de banda caracterizado porque comprende dos secciones conectadas en serie en el que la frecuencia de pérdida máxima en la primera sección, está dispuesta para ocurrir al valor requerido cuando la corriente de entrada a esa sección es igual o algo menor que la corriente máxima que ocurriría en la práctica y la segunda sección está ajustada similarmente para atender a la corriente menor que esta sección recibe.
