Hello Bob,

how are you?

we have been in touch some months ago
regarding Seismowin software with the DATAQ board.
We spoken also about the inverse filtering to enanhce
the low frequency response of the 4.5Hz geophone.
Do you remember?

Have you used Seismowin anymore?

I doing some revisions on Seismowin and I would also
add a better inverse filter (better than the one I already have).

I remember that you realized an inverse filter and probably
also sent me a copy of the code.
I found a fragment of code in the PSN archives.

What is the situation of the filter you designed?
Can you kindly update me on it?

cheers
mauro
