Abstract

EL FILTRO PRESENTA UN DISPOSITIVO (4) PARA FORMAR UNA PRIMERA Y UNA SEGUNDA SEÑAL (U1, U2) A PARTIR DE UNA SEÑAL A FILTRAR (U). UNA DIFERENCIA ENTRE ESTA PRIMERA Y SEGUNDA SEÑALES (U1,U2) ES AJUSTABLE. EN UN DISPOSITIVO DE SUBSTRACCION (5) SE SUBSTRAE LA SEGUNDA SEÑAL DE LA PRIMERA SEÑAL (U1) Y LA SEÑAL DIFERENTE RESULTANTE (U1-U2) ES CONDUCIDA A UN DISPOSITIVO (6) DEPENDIENTE DE LA FRECUENCIA CON UNA CARACTERISTICA DE TRANSMISION DE FILTRADO H(S). EN UN DISPOSITIVO DE ADICION (7) SE FORMA A PARTIR DE UNA PRIMERA SEÑAL (U1) Y UNA SEÑAL (U3) EXTRAIBLE EN LA SALIDA (8) DEL DISPOSITIVO (6) DEPENDIENTE DE LA FRECUENCIA UNA SEÑAL DE SUMA (U$) QUE AL MISMO TIEMPO REPRESENTA LA SEÑAL DE SALIDA DEL FILTRO. LA PENDIENTE DE FLANCOS AJUSTABLE DEL FILTRO RESULTA POR LA VARIACION DE LA SEÑAL DE LA DIFERENCIA (U1-U2).
