Hi List,

I am very interested in the overdamped approach to extending the
response of a geophone.

I have placed a very simple analysis on-line here:

  http://www.c-c-i.com/2.00461568015544/

The input listing and tabular results are in the 'Text Output' link.
The first run is for the critically damped phone.  Scroll past the first
set of output data for the listing for a damping factor of 10 - which
results in a negative load resistor.

Response plots are in the .png files.
