Abstract

PERFECCIONAMIENTOS EN UN MONTAJE AMPLIFICADOR DE CORRIENTE CONTINUA. CONSISTENTES EN QUE: LAS ENTRADAS NO INVERSORAS (A) DE LOS AMPLIFICADORES (A1 Y A2) ESTAN CONECTADAS A LOS BORNES DE ENTRADA DEL MONTAJE, A TRAVES DE MEDIOS DE CONMUTACION (1), PARA PERMITIR, SELECTIVAMENTE, LA INVERSION DE POLARIDAD DE ESTA CONEXION; ESTA DOTADO DE MEDIOS PARA DETERMINAR CICLOS DE FUNCIONAMIENTO SUCESIVOS, QUE COMPRENDEN UN CICLO DE MEDIDA Y UN CICLO DE CALCULO, UNA MEMORIA (7) PARA MEMORIZAR DURANTE CADA CICLO DE FUNCIONAMIENTO LA SEÑAL DE SALIDA DEL SEGUNDO AMPLIFICADOR (A2), QUE RESULTA DE UNA SEÑAL DE ENTRADA RECIBIDA EN UNA PRIMERA POSICION DE LOS MEDIOS DE CONMUTACION, Y UN CIRCUITO DE CALCULO (5) QUE RECIBE, CUANDO LOS MEDIOS DE CONMUTACION (1) ESTAN EN UNA SEGUNDA POSICION, LA SEÑAL DE SALIDA DEL SEGUNDO AMPLIFICADOR (A2).
