The active microfilter is essentially composed of an active part, which comprises a sign inverter circuit composed of an operational amplifier (13), two resistances and the impedance to be adapted (12), and a passive part which comprises capacitors, coils and resistances. The active microfilter is arranged in an auto-installable device which comprises a circuit for supplying the active part; wherein the aim is to eliminate the reflections caused by line sections, without adaptation, which interfere with the correct operation of the network when accessing broadband with the VDSL2 standard. |
