Abstract

SE TRATA DE UN CIRCUITO ELECTRONICO PARA INTERROGAR UN RECEPTOR (8) A DISTANCIA MEDIANTE UNA LINEA DE DOS HILOS (9) Y PARA DETECTAR LAS SEÑALES DE RESPUESTA (S2) EMITIDAS POR ESTE RECEPTOR, CONSTANDO DICHO CIRCUITO DE ELEMENTOS (7) PARA COMPARAR CON UNA TENSION DE REFERENCIA LA TENSION REAL (U'') QUE DEFINE DICHAS SEÑALES DE RESPUESTA. ESTA TENSION DE REFERENCIA ES UNA TENSION VARIABLE PONDERADA (P) OBTENIDA POR FILTRADO DE PASO BAJO, EN UN CIRCUITO RESISTENCIA (12)-CAPACIDAD (13), DE LA MENCIONADA TENSION REAL.
