Abstract
CIRCUITO PARA RELES DE INTENSIDAD CON CARACTERISTICA A TIEMPO INVERSO. EL CIRCUITO ESTA COMPUESTO POR LA UNIDAD DE ENTRADA (1), UNA UNIDAD DE MEDIDA INSTANTANEA (2) Y OTRA DE MEDIDA TEMPORIZADA (3), UN GENERADOR DE CARACTERISTICA (4) Y UNA UNIDAD DE TEMPORIZACION ADICIONAL (5). LA UNIDAD DE ENTRADA (1) DA UNA MUESTRA CUANTITATIVA DE LA SEÑAL DE ENTRADA. CON LAS RESISTENCIAS (12), O EN SU CASO ELEMENTOS NO LINEALES, SE PUEDE VARIAR LA CURVA CARACTERISTICA A TIEMPO INVERSO Y ESTA ADEMAS PUEDE VER DESPLAZADA CON LA UNIDAD DE TEMPORIZACION ADICIONAL. LA VUELTA A CERO DEL GENERADOR DE CARACTERISTICA PUEDE REGULARSE CON LA RESISTENCIA (13). EN REPOSO EL CIRCUITO NO CONSUME ENERGIA DE LA FUENTE AUXILIAR GRACIAS AL MONTAJE COMPLEMENTARIO DE LOS TRANSISTORES (9) A LOS TIRISTORES (21) Y A LA POSICION DE LA CUCHILLA (11).
