Abstract

UN SISTEMA DE SINCRONIZACION PARA VARIOS REPRODUCTORES DE CD (12), (14), (16) Y (18) INCLUYE UN CONTROLADOR (20) QUE GENERA CUATRO FRECUENCIAS DE MUESTREO SEPARADAS PARA LA CONEXION A LAS ENTRADAS DEL RELOJ DE PALABRA DE LOS REPRODUCTORES DE CD. UN RELOJ DE PALABRA PRINCIPAL EMITE UNA SEÑAL DE RELOJ PRINCIPAL QUE SE INTRODUCE EN EL REPRODUCTOR DE CD (12) Y LUEGO ES MULTIPLICADA POR UN MULTIPLICADOR (40). LA SALIDA DEL MULTIPLICADOR (40) ESTA DIVIDIDA POR DIVISORES VARIABLES (48), (50) Y (52) PARA PROPORCIONAR LAS FRECUENCIAS DE MUESTREO A LOS REPRODUCTORES DE CD RESTANTES (14), (16) Y (18). CADA UNO DE LOS DISCOS (54) TIENE UNA CABECERA (80) COLOCADA AL PRINCIPIO DE CADA UNA DE LAS PISTAS DE PROGRAMA. ESTA CABECERA TIENE UNA SEÑAL DE SINCRONIZACION UNICA ASOCIADA A ELLA QUE EMITE LOS DATOS CORRESPONDIENTES A LA POSICION DE LOS DATOS DIGITALES DE SALIDA. DURANTE LA EMISION DE LOS DATOS ASOCIADOS CON LA CABECERA, SE DETERMINA UNA DIFERENCIA ENTRE LAS POSICIONES DE LOS DIFERENTES REPRODUCTORESDE CD. ESTA DIFERENCIA SE ALMACENA EN EL CONTROLADOR (20) Y LUEGO LAS RELACIONES DE DIVISION DE CADA UNO DE LOS DIVISORES (48), (50) Y (52) SE AJUSTAN PARA CAMBIAR LA FRECUENCIA DE MUESTREO EN SU SALIDA, CON LO QUE RESULTA UN DESLIZAMIENTO DE MUESTRAS, HASTA QUE LA DIFERENCIA ENTRE LOS MARCOS DE MUESTREO DE CADA UNO DE LOS REPRODUCTORES DE CD SE ESTABLECE EN CERO.
