Abstract
PARA MEJORAR LA PRECISION DE PONDERACION Y LA VELOCIDAD DE PONDERACION DE UN APARATO PARA PESAR, UN CONVERTIDOR DE AD DEL TIPO DELTA-SIGMA (4) CUYA FRECUENCIA DE CORTE ES MAYOR QUE LA DE UN FILTRO ANALOGICO (3) SE CONECTA AL FILTRO ANALOGICO (3) EN EL LADO CORRIENTE ABAJO DEL MISMO. PARA LLEVAR A CABO DE MANERA RAPIDA LA CORRECCION DE DERIVA DE UN AMPLIFICADOR (2), HAY UN ELEMENTO DE CORRECCION (52) ADAPTADO PARA CONFIGURAR EL FILTRO ANALOGICO (3) DE MODO QUE PUEDA PASAR DE UNA FUNCION DE FILTRADO EN UN MODO DE PONDERACION A UNA FUNCION DE TAMPONAMIENTO EN UN MODO DE CORRECCION, ALMACENAR UNA SEÑAL, QUE SE OBTIENE DEL CONVERTIDOR DE AD DEL TIPO DELTA-SIGMA (4) CUANDO SE ENCUENTRA EN EL MODO DE CORRECCION, COMO UNA SEÑAL DE DERIVA DF Y OBTENER UNA SEÑAL DE PONDERACION CORREGIDA D2 QUE SE OBTIENE A BASE DE RESTAR LA SEÑAL DE DERIVA DF DE UNA SEÑAL DE PONDERACION D1 OBTENIDA DEL CONVERTIDOR DE AD DEL TIPO DELTA-SIGMA (4) CUANDO SE ENCUENTRA EN EL MODO DE PONDERACION.
