Abstract

UN CIRCUITO DE PROCESAMIENTO DE SEÑAL DIGITAL QUE SIRVE PARA SOPORTAR DIFERENTES ARREGLOS DE UN TAMBOR ROTATIVO O SIMILAR MEDIANTE LA ADAPTACION DEL CIRCUITO PARA LA SALIDA DE UNA SEÑAL DE GRABACION EN UNA SINCRONIZACION CONMUTADA EN COONCORDANCIA CON LA ESTRUCTURA DEL TAMBOR ROTATIVO Y/O SIMILAR. EL CIRCUITO DE PROCESAMIENTO DE SEÑAL DIGITAL COMPRENDE MEDIOS DE MEMORIA PARA ALMACENAMIENTO DE DATOS DE CONTROL REPRESENTATIVOS DEL DIAMETRO DEL TAMBOR ROTATIVO, LA SOLAPA DE LA CINTA MAGNETICA ENRROLLADA ALREDEDOR DEL TAMBOR ROTATIVO Y EL ARREGLO DE CABEZAS MAGNETICAS SOBRE EL TAMBOR ROTATIVO; ASI COMO MEDIOS CONECTADOS A LA MEMORIA Y CORRESPONDIENTES A DATOS DE CONTROL ALMACENADOS PARA LA SALIDA DE LA SEÑAL DE GRABACION EN UNA VELOCIDAD DE TRANSMISION ESPECIFICA Y EN UNA TEMPORIZACION CONMUTADA COMO UNA FUNCION DE LOS DATOS ALMACENADOS EN LOS MEDIOS DE MEMORIA.
