Abstract

PARA IDENTIFICAR AUTOMATICAMENTE EL TIPO DE CONTADOR DE REGISTRO OPTICO PARA SER LEIDO, EL DATO SEÑAL (HF), QUE CONTIENE EL DATO ALMACENADO POR MEDIO DE PITS, ES ALIMENTADO A LA PRIMERA ENTRADA DE UN PRIMER COMPARADOR (V1) VIA UN HIGH-PASS (H) Y UN RECTIFICADOR (G) CONECTADO EN SERIE CON EL ULTIMO, Y LA SEGUNDA ENTRADA DEL MENCIONADO COMPARADOR, VIA UN LOW-PASS (T). UN VOLTAJE DE REFERENCIA (VR) SE APLICA A LA SEGUNDA ENTRADA DE UN SEGUNDO COMPARADOR (V2), LA PRIMERA ENTRADA DE LAS CUALES SE CONECTA A LA SALIDA DEL RECTIFICADOR (G) O AL LOW-PASS (T). LAS SALIDAS DE LOS COMPARADORES (V1, V2) ESTAN CONECTADAS A UN PROCESADOR DE CONTROL (SP) QUE , SOBRE LA BASE DE LAS SEÑALES DE ENTRADA DE LOS DOS COMPARADORES (V1, V2), IDENTIFICA EL TIPO DE PORTADOR DE REGISTRO OPTICO QUE HA SIDO INSTALADO EN EL EQUIPO. SE APLICA EN REGISTROS OPTICOS Y MAGNETOOPTICOS Y EQUIPOS DE REPRODUCCION.
