Abstract

PARA LA RECUPERACION DE UN BITACTO DE ESTE TIPO SE CREA UN BITACTO DE LADOS RECEPTORES MEDIENTA UN EMISOR DE TACTOS (TG) Y UN CONTADOR (Z) CON LA FRECUENCIA DE LA SEÑAL A RECIBIR. MEDIANTE UNA LOGUCA VALORACION DE FASES (PAL) SE VALORA LA POSICION TEMPORAL DEL FLANCO ASCENDENTE DE UN IMPULSO RECIBIDO EN COMPARACION CON UNA POSCION TEMPORAL PREVISTA DE FLANCO DE IMPULSOS EFECTIVO PRODUCIDO POR EL BITACTO. EN EL CASO SINCRONICO EL FLANCO DE IMPULSOS EFECTIVO VISTO EN TIEMPO ESTA SITUADO EN EL CENTRO DEL IMPULSO RECIBIDO (PALPADO MEDIO BIT). POR MOTIVO DE PROPIEDADES DE POTENCIA NO IDEALES PUEDE OSCILAR LA DURACION DE LOS PIMPULSOS RECIBIDOS EN EL VALOR DEBIDO. PARA PODER DISTINGUIR UNA SERIE DE FLANCOS MOMENTANEA DE UN IMPULSO RECIBIDO (DEMASIADO LARGO O DEMASIADO CORTO) DE UN APLAZAMIENTO DE FASES REAL SE TRANSMITE AHORA LA POSICION TEMPORAL DEL FLANCO ASCENDENTE Y DESCENDENTE DE CADA IMPULSO. SI EXISTE UN IMPULSO DE UNA DURACION DEBIDA DESVIADA EN CORTO O DEMASIDO LARGO, PERO QUE SEA SIMETRICO A LA POSICON TEMPORA PREVISTA DEL FLANCO DE IMPULSO EFECTIVO DEL BITACTO CREADO, ENTONCES SE TRATA DE UNA SECUENCIA DE FLANCOS MOMENTANEA, DE MANERA QUER NO ES NECESARIA UNA CORRECCION DE FASES.
