Abstract

CIRCUITO PARA LA SUPRESION DE SEN/ALES PARASITAS.SE COMPONE DE UN DIODO (1) SENSIBLE A LA LUZ EN SERIE CON UNA RESISTENCIA (2) ENTRE UNA FUENTE ESTABILIZADA (UB) Y UN POTENCIAL DE REFERENCIA. DE LA UNION DEL DIODO CON R2 SALE UNA TOMA A UN AMPLIFICADOR (V1) ALIMENTADO COMO EL CIRCUITO ANTERIOR Y CUYA SALIDA SE RECTIFICA EN (3) Y PASAN AL CIRCUITO RC (4, 6, 5) CON UNA CONSTANTE DE TIEMPO Y DEL CONDENSADOR (6) AL RC (7, 5) CON OTRA CONSTANTE DE TIEMPO PROPIA Y DE AQUI AL TRANSISTOR V2, CUYA TENSION CONTINUA DE BASE NUNCA ES MENOR QUE LA DE LA FUENTE MENOS LA BASE-EMISOR DEL TRANSISTOR, POR LO QUE RESULTA LA SEN/AL DIGITAL SIN RUIDO APRECIABLE ENTRE LA RESISTENCIA DE COLECTOR (R9) Y LA TENSION DE REFERENCIA.TIENE APLICACION COMO ELIMINADOR DE IMPULSOS DE RUIDO INDESEABLE EN CIRCUITOS MUY SENSIBLES, COMO LOS CONTROLADOS POR MICROPROCESADOR.
