Abstract

UN GENERADOR DE SEÑAL TIENE UN OSCILADOR (52) DE REFERENCIA VARIABLE, UN OSCILADOR (54) VARIABLE Y UN BUCLE (56) DE FASE BLOQUEADA PARA GENERAR UNA SALIDA CON FLUCTUACION Y VARIACION. EL OSCILADOR (52) DE REFERENCIA VARIABLE GENERA UNA REFERENCIA QUE TIENE UN DESPLAZAMIENTO DE FASE VARIABLE PARA UN PRIMER INTERVALO DE FRECUENCIA DE MODULACION DE FASE Y UNA SALIDA CONSTANTE PARA UN SEGUNDO INTERVALO DE FRECUENCIA DE MODULACION DE FASE. EL OSCILADOR (54) VARIABLE GENERA UNA SALIDA CONSTANTE PARA EL PRIMER INTERVALO DE FRECUENCIA DE MODULACION DE FASE Y UNA SALIDA VARIABLE PARA UN SEGUNDO INTERVALO DE FRECUENCIA DE MODULACION DE FASE. EL BUCLE (56) DE FASE BLOQUEADA INCLUYE UN DETECTOR (74) DE FASE, UN NODO (76) DE SUMA DE FASES Y UN OSCILADOR (80), ESTANDO EL DETECTOR (74) DE FASE ACOPLADO PARA RECIBIR LAS SALIDAS DEL OSCILADOR (52) DE REFERENCIA VARIABLE Y DEL OSCILADOR (80), ESTANDO EL NODO (76) DE SUMA DE FASES ACOPLADO PARA RECIBIR LAS SALIDAS DEL OSCILADOR (54) VARIABLE Y DEL DETECTOR (74) DE FASE. LA SALIDA DEL BUCLE (56) DE FASE BLOQUEADA RASTREA EL OSCILADOR (52) DE REFERENCIA VARIABLE PARA EL PRIMER INTERVALO DE FRECUENCIA DE MODULACION DE FASE Y GENERA UNA SALIDA DE FASE MODULADA EN RESPUESTA A LA SALIDA VARIABLE DEL OSCILADOR (54) VARIABLE PARA EL SEGUNDO INTERVALO DE FRECUENCIA DE MODULACION DE FASE.
