Abstract

EL SINTONIZADOR (10) INCLUYE UN PRIMER DIVISOR (16) PARA DIVIDIR UNA PRIMERA SEÑAL EMITIDA POR UNA FUENTE DE FRECUENCIA DE REFERENCIA (12). HAY UN PRIMER CIRCUITO DE SINCRONIZACION DE FASE (20) QUE RECIBE UNA PRIMERA SEÑAL DIVIDIDA PROCEDENTE DEL PRIMER DIVISOR (16) Y QUE PROPORCIONA UNA SEÑAL DE FRECUENCIA INTERMEDIA EN RESPUESTA A LA MISMA. EL PRIMER CIRCUITO DE SINCRONIZACION DE FASE (20) INCLUYE UN PRIMER DETECTOR DE FASE (22) QUE COMPARA LA FASE DE LA PRIMERA SEÑAL CON LA FASE DE UNA PRIMERA SEÑAL DE REALIMENTACION Y PROPORCIONA UNA PRIMERA SEÑAL DE DESFASE EN RESPUESTA A LA MISMA. EL PRIMER CIRCUITO DE SINCRONIZACION DE FASE (20) INCLUYE UN PRIMER OSCILADOR CONTROLADO POR TENSION (30) QUE PROPORCIONA LA SEÑAL INTERMEDIA EN RESPUESTA A LA PRIMERA SEÑAL DE DESFASE. EL PRIMER CIRCUITO DE SINCRONIZACION DE FASE (20) INCLUYE UN PRIMER MEZCLADOR (32) QUE MEZCLA LA SEÑAL INTERMEDIA CON UNA SEGUNDA SEÑAL A UNA SEGUNDA FRECUENCIA F2 Y PROPORCIONAR LA PRIMERA SEÑAL DE REALIMENTACION EN RESPUESTA A LA MISMA. EN EL PRIMER CIRCUITO DE SINCRONIZACION DE FASE (20) HAY UN SEGUNDO DIVISOR (38) QUE DIVIDE LA PRIMERA SEÑAL DE REALIMENTACION ANTES DE SU APLICACION AL PRIMER DETECTOR DE FASE (22). HAY UN TERCER DIVISOR (39) QUE DESPLAZA LA FRECUENCIA DE LA SEÑAL DE FRECUENCIA INTERMEDIA Y HAY UN SEGUNDO CIRCUITO DE SINCRONIZACION DE FASE (40) ACOPLADO AL TERCER DIVISOR QUE PROCESA LA SEÑAL DE FRECUENCIA INTERMEDIA MANIPULADA EN FRECUENCIA Y PROPORCIONA UNA SEÑAL DE FRECUENCIA DE SALIDA DESDE EL SINTONIZADOR. EL SEGUNDO CIRCUITO DE SINCRONIZACION DE FASE (40) INCLUYE UN SEGUNDO DETECTOR DE FASE (42) QUE COMPARA LA FASE DE LA SEÑAL INTERMEDIA MANIPULADA CON LA FASE DE UNA SEGUNDA SEÑAL DE REALIMENTACION Y PROPORCIONA UNA SEGUNDA SEÑAL DE DESFASE EN RESPUESTA A LA MISMA. HAY UN SEGUNDO OSCILADOR CONTROLADO POR TENSION (50) QUE PROPORCIONA LA SEÑAL DE FRECUENCIA DE SALIDA DESDE EL SINTONIZADOR (10). EL SINTONIZADOR ES ADECUADO PARA IMPLEMENTARLO EN, POR EJEMPLO, SISTEMAS DE TELECOMUNICACIONES YDE RADAR.
