Abstract

DISPOSITIVO PARA QUE LAS CURVAS DE SEÑAL MANTENGAN UNA SIMETRIA, CONCRETAMENTE LOS GENERADORES DE FRECUENCIA (5) SEGUN LA CLASE DE GENERADORES DE RELOJ QUE TIENEN UN SISTEMA DE ENTRADA, CONCRETAMENTE UN GENERADOR DE UNION, QUE LLEVA HACIA UN DIVISOR DE FRECUENCIA (2), CUYO FACTOR DIVISOR SE AJUSTA SOBRE EL VALOR RECIPROCO DE UN FACTOR MULTIPLICADOR CON RESPECTO A LA FRECUENCIA BASE ESTABLECIDA DEL SISTEMA O DEL GENERADOR DE FRECUENCIA. SU SALIDA O POR MEDIO DE LA INTERCALACION DE OTROS ELEMENTOS LLEVA A LA SALIDA DEL DISPOSITIVO.
