Abstract
EN UNA DISPOSICION DE CIRCUITO PARA LA GENERACION DE UNA TENSION DE SINCRONIZACION PARA UN OSCILADOR EN UN RECEPTOR DE RADIODIFUSION CON LA AYUDA DE UN BUCLE DE REGULACION DE FASE SE CONSIGUE UNA CONMUTACION DEL FILTRO DE RECTIFICADO DE TAL MODO, QUE LA FRECUENCIA LIMITE DEFINIDA A TRAVES DE UNA AMPLIFICACION DE RECTIFICADO DE 1 SE MODIFICA A TRAVES DE LA CONMUTACION, SIN QUE SE MODIFIQUE ESENCIALMENTE LA DEPENDENCIA DE LA AMPLIFICACION DE LA FRECUENCIA EN LA ZONA DE LA FRECUENCIA LIMITE.
