Abstract

CIRCUITO TRANSMISOR DE INFRARROJOS CAPAZ DE RESPONDER A UNOS IMPULSOS DE ENTRADA Y DE GENERAR UNOS IMPULSOS DE TRANSMISION DE RAYOS INFRARROJOS. CONSTA DE UN EXCITADOR LOGICO (11) DE DOBLE TRANSISTOR, ACOPLADO POR MEDIO DE UNA RESISTENCIA (13) A LA BASE DE UN TRANSISTOR (10) DE TIPO NPN; DE UN DIODO EMISOR DE INFRARROJOS (5) QUE ES ACTIVADO MEDIANTE EL TRANSISTOR NPN (10) A TRAVES DE SU TRAYECTO DE COLECTOR-EMISOR, QUE INCLUYE TAMBIEN UNA RESISTENCIA (15); Y DE UN DIODO EMISOR DE LUZ (14) QUE DESEMPEÑA DOS FUNCIONES, EN PRIMER LUGAR OFRECE UNA INDICACION VISIBLE DE TRANSMISION, Y EN SEGUNDO LUGAR PROPORCIONA UN NIVEL DE TENSION DE REFERENCIA PARA DETERMINAR LAS CARACTERISTICAS DE TRABAJO DEL DIODO EMISOR DE INFRARROJOS (5) Y DEL CIRCUITO DE TRANSISTOR.
