I am thinking of building a new amplifier
and was wondering if this profile is correct
for a short period (1Hz) type.
a N6 low pass mfb three stage filter would go
after the stage crating this profile at about
2.5 or 3 Hz.
One of you guys must be technical whizz and
help me out here in making a decision.
I do not expect to fully compensate for
the rolloff of the geophone.
just trying to get a better picture.
these were made using the LT_SPICE_IV simulator program and
I will put the models up if you wish to see them.
but you need the program to make the models work.
