Abstract

UN CIRCUITO COMPENSADOR 2 DEL RETRASO DE CAPTACION PROVEE UN SENSOR MODIFICADO DE SEÑAL DE TEMPERATURA PARA SER UTILIZADO SUBSIGUIENTEMENTE EN EL CONTROL DE LAS TEMPERATURAS CAPTADAS. EL CIRCUITO COMPENSADOR 2 COMPARA DIGITALMENTE UNA SEÑAL REPRESENTATIVA DE LA TEMPERATURA CAPTADA ACTUAL CON UNA SEÑAL DE TEMPERATURA CAPTADA EN EL TIEMPO DE MUETREO ULTIMO O PRECEDENTE PARA PRODUCIR UNA SEÑAL DE DIFERENCIA QUE SE CONVIERTE EN UNA SEÑAL DE PENDIENTE DE CAPTACION 16 Y SE MULTIPLICA POR UNA CONSTANTE DE TIEMPO DE CAPTACION 18. LA SEÑAL RESULTANTE SE PASA A TRAVES DE UN FILTRO 20 PARA ELIMINAR LOS EFECTOS TRANSITORIOS Y SE SUMA A LA SEÑAL DE TEMPERATURA CAPTADA ORIGINALMENTE PARA PROVEER UNA SEÑAL DE TEMPERATURA CAPTADA PARA CONTROLAR LA TEMPERATURA POR LO QUE LA TEMPERATURA CAPTADA ES UNA MEJOR ESTIMACION DE LA TEMPERATURA AMBIENTAL ACTUAL CONTROLADA POR UN TERMOSTATO QUE UTILIZA LA SEÑAL DE TEMPERATURA CAPTADA.
