Re: impedance calculations

[Melinda Piket-May <mjp@maori.Colorado.EDU>]

When you plot impedance in the time domain using a gaussian, you need to
pick off the impedance at the peak of the pulse.  The other option is to
look in the frequency domain, in which case you should get what you are
looking for.

Please let me know if this still does not work for you.
