Abstract of the Disclosure The invention concerns a one-port RC subnetwork for active filter ladder networks. The subnetwork includes a single pair of terminals, to one of which there is applied a reference potential, the subnetwork consisting of an operational amplifier having an input point and an output point. A first capacitor and a second capacitor are connected in series between the single pair of terminals and a feedback path from the output point of the amplifier with the parallel circuit of a first resistor and a third capacitor to the junction of the first and second capacitors. The first resistor and the third capacitor are dimensioned so that the feedback path has an effective time constant essentially equal to the time constant of the amplifier in the fall-off region of gain-frequency characteristic thereof in order to extend the effective band width of the subnetwork, so that in the equivalent circuit the series circuit of the subnetwork further comprises in series: a parallel connection of two elements each having a complex impedance l/bs.
