Abstract

EL DISPOSITIVO ESTA DISEÑADO PARA PROCESAR SEÑALES DE SENSOR SUMINISTRADAS MEDIANTE UN SENSOR DE MEDICION (1) Y OTRO U OTROS SENSORES (4). EL SENSOR DE MEDICION (1) GENERA UN EFECTO DE MEDIDA M QUE DEPENDE FUNDAMENTALMENTE DE LA INTERFERENCIA FISICA QUE SE VA A ADQUIRIR. EL DISPOSITIVO RECIBE LOS EFECTOS DE MEDIDA EN FORMA DE VALORES DE ENTRADA Y MEDIANTE EL PROCESAMIENTO ANALOGO DE LAS SEÑALES DEL SENSOR, SUMINISTRA UN VALOR DE SALIDA S CUYA PROPORCION CON RESPECTO A UN VALOR DE REFERENCIA S SUB REF QUE DEPENDE DE LOS EFECTOS DE MEDIDA FORMADOS EN LOS VALORES DE ENTRADA, SE DETERMINA MEDIANTE UNA FUNCION DE TRANSMISION DEFINIDA DE FORMA ESPECIAL. LOS COEFICIENTES DE LA FUNCION DE TRANSMISION SON AJUSTABLES Y DEPENDEN DE LAS PROPIEDADES DEL SENSOR DE MEDIDA (1) PARA OBTENER LA FUNCION DE TRANSMISION DESEADA, MEDIANTE LA CUAL, EL EFECTO DE LA INTERFERENCIA SOBRE SU EFECTO DE MEDIDA QUEDA COMPENSADO Y SE CORRIGEN LOS ERRORES ENTRE LA MEDIDA Y EL EFECTO DE MEDIDA M1.
