The Cauer networks generally have physical significance
and may be divided between nodes to separate thermal
behavior due to one portion of the network from another.
The Foster networks, though when sorted by time constant
circuit simulating tools, whereas Foster networks may be
more easily implemented using mathematical tools (for
instance, in a spreadsheet program), according to the
following formula:
(as above) bear a rough correlation with the Cauer networks,
are really only convenient mathematical models. Both

Time constants are not simple RC products. Amplitudes
of mathematical solution are not the resistance values.
