Overshooting circuit ?

[patchell]

    Well, another posibility, if you want to keep it as simple as
posible, is to use a Sallen and Key Low pass filter.  This will give you
a two pole filter, and the damping is sorta easy to control, but it
changes the gain of the filter.  Anyway, it consists on a single opamp,
two resistors to set the gain, and two resistors and two capacitors for
tuning the frequency.  This filter does not lend itself to voltage
control, but you could use pots.

    I don't have a circuit diagram handy, if you are interested, I can
draw one up without too much inconveinence.
