Wilhelm Cauer proposed a number of electronic filter designs or circuit topologies for realization of a driving point impedance.
[edit] Cauer's forms of driving point impedances
Cauer's first form of driving point impedance consisted of shunt capacitors and series inductors. If we take an output at the far end of the driving point impedance so-realized, we end up with a low pass filter.
Cauer's second form consisted of series capacitors and shunt inductors. If we take an output at the far end of the driving point impedance so-realized, we end up with a high pass filter.
