Abstract

LA PRESENTE INVENCION SE REFIERE A UN CIRCUITO DE MEDIDA QUE DA EL VALOR NUMERICO DE UNA SEÑAL ELECTRICA ANALOGICA. EL CIRCUITO DE MEDIDA NUMERICA DE UNA SEÑAL ELECTRICA ANALOGICA PRODUCE UNA SEÑAL DE MEDIDA (M) Y SE COMPONE DE UN AMPLIFICADOR (1) QUE RECIBE ESTA SEÑAL ELECTRICA (I) SEGUIDA DE UN CONVERTIDOR ANALOGICO-NUMERICO (2) LIBERANDO UN DATO NUMERICO (N). ESTE AMPLIFICADOR (1) PRESENTA UNA GANANCIA CONTROLADA POR UNA SEÑAL DE CONTROL (C), PUDIENDO ESTA GANANCIA TOMAR AL MENOS DOS COLORES. EL CIRCUITO DE MEDIDA CONSTA TAMBIEN DE UNA UNIDAD DE CONTROL (3) QUE PRODUCE ESTA SEÑAL DE CONTROL, MEMORIZANDO LOS DATOS NUMERICOS QUE CORRESPONDEN A LOS DISTINTOS VALORES DE LA GANANCIA Y COMPUESTO TAMBIEN POR MEDIOS PARA PRODUCIR ESTA SEÑAL DE MEDIDA (M) A PARTIR DE ESTOS DATOS NUMERICOS (N).
