Abstract
UN CIRCUITO DETECTOR DE SEÑAL DE IMPULSO ESTA ADAPTADO A UN SISTEMA DE REPRODUCCION DE IMAGENES QUE TIENE UN CIRCUITO DESPLEGADOR DE FRECUENCIA PARA GENERAR UNA SEÑAL DE LUMINANCIA DESPLEGADA DESPLEGANDO UN COMPONENTE DE ALTA FRECUENCIA REPLEGADO DENTRO DE UN COMPONENTE DE BAJA FRECUENCIA A SU BANDA DE FRECUENCIA ORIGINAL PARA REPRODUCIR UNA SEÑAL DE IMAGEN DE ANCHO DE BANDA COMPLETO EN EL CUAL EL COMPONENTE DE ALTA FRECUENCIA HA SIDO PLEGADO DENTRO DEL COMPONENTE DE BAJA FRECUENCIA Y GRABADO SOBRE UN MEDIO DE GRABACION QUE TIENE UN ANCHO DE BANDA LIMITADO. EL CIRCUITO DETECTOR COMPRENDE UN PREFILTRO (100) PARA ELIMINAR EL PORTADOR REPLEGADO CONTENIDO EN LA SEÑAL DE LUMINANCIA DESPLEGADA Y LAS BANDAS LATERALES DEL MISMO Y UN FILTRO DE CARACTERISTICA EN PEINE (110) PARA DETECTAR UNA SEÑAL DE IMPULSO QUE ES EL COMPONENTE DIFERENCIAL ENTRE TOMAS EN UNA SEÑAL DE LUMINANCIA DESPLEGADA MEDIANTE EL FILTRADO DE LA SALIDA DEL PREFILTRO.
