Abstract

UN SINTETIZADOR DE FRECUENCIA (10) COMPRENDE SISTEMA OSCILADOR DE FRECUENCIA DE REFERENCIA (11) PARA DAR UNA SEÑAL DE FRECUENCIA DE REFERENCIA (51) Y UN BUCLE DE FASE PRIMERA (12) ACOPLADO AL SISTEMA OSCILADOR DE FRECUENCIA DE REFERENCIA PARA GENERAR UNA SEÑAL SINTETIZADA PRIMERA (52) EN UNA FRECUENCIA SELECCIONABLE DE UNA SERIE DE FRECUENCIAS DESEADAS, CADA UNA DE LAS CUALES DIFIERE DE LA ADYACENTE EN UN TAMAÑO DE PASO DE FRECUENCIA BASICAMENTE UNIFORME. ADEMAS, SE DISPONE UN BUCLE CERRADO DE FASE SEGUNDO (13) ACOPLADO AL SISTEMA OSCILADOR DE FRECUENCIA DE REFERENCIA (11) Y AL BUCLE DE FASE PRIMERA (12) PARA GENERAR UNA SEÑAL DE SALIDA (57) CON UNA FRECUENCIA PREDETERMINADA. EL BUCLE DE FASE SEGUNDO (13) COMPRENDE SISTEMA OSCILADOR SEGUNDO (32) PARA GENERAR UNA SEÑAL DE SINTETIZADOR SEGUNDA (53) EN UNA FRECUENCIA SELECCIONABLE DE UNA SERIE DE FRECUENCIAS DESEADAS, SISTEMA DIVISOR PRIMERO (33) ACOPLADO AL SISTEMA OSCILADOR SEGUNDO (32) PARA DIVIDIR LA SEÑAL SINTETIZADA SEGUNDA (53) POR UN NUMERO FIJO PREDETERMINADO PRIMERO PARA DAR UNA SEÑAL DE SINTETIZADOR SEGUNDA DIVIDIDA (54), SISTEMA MEZCLADOR (34) ACOPLADO AL OSCILADOR DE FRECUENCIA DE REFERENCIA (11) Y AL SISTEMA DIVISOR PRIMERO (33) PARA MEZCLAR LA SEÑAL DE SINTETIZADOR SEGUNDA DIVIDIDA (54) CON UNA SEÑAL ARMONICA PREDETERMINADA DE LA SEÑAL DE FRECUENCIA DE REFERENCIA (51) PARA DAR UNA SEÑAL DE FRECUENCIA DESPLAZADA (55), SISTEMA DIVISOR SEGUNDO (31) ACOPLADO AL BUCLE DE FASE PRIMERO (12) PARA DIVIDIR LA SEÑAL SINTETIZADA PRIMERA (52) POR UN NUMERO FIJO PREDETERMINADO SEGUNDO PARA DAR UNA SEÑAL DE FRECUENCIA DE REFERENCIA SEGUNDA DIVIDIDA (56) CON UN TAMAÑO DE PASO DE FRECUENCIA REDUCIDO Y RUIDO DE FASE REDUCIDO. ADEMAS SE DISPONE UN SISTEMA DETECTOR DE FASE (41) ACOPLADO AL SISTEMA MEZCLADOR (34) Y AL SISTEMA DIVISOR SEGUNDO (31) PARA CERRAR LA SEÑAL DE FRECUENCIA DESPLAZADA (55) A LA SEÑAL DE FRECUENCIA DE REFERENCIA SEGUNDA DIVIDIDA (56).
