Hello PSN,

I am now injecting into my data through software a 3Hz very low signal
summed with data to show in your spectrum displays
of my data exactly where three Hz is supposed to be.

The signal is so low, like +/- 1 count out of 2047 you most probably
will not see it without the FFT display.

I also average out DC drift caused by hardware
faults this same way.

I would like to hear comments as to what
you think of doing such a thing.

Please feel free to email me directly
if others do not want to be bothered
by such software discussions.

I can right away see according to winquake
that the sample rate and ideal signal
do not exactly match yet are extremely close.
I do not wish to change anything
yet possibly I may be able to
obtain a more accurate sample rate
by matching the expected rate with the ideal
signal from the Winquake FFT display.

These modified data files will now be
what I am posting here at PSN
EVENT database.

It is simply my hope to make
something (the data) easier to read
through the data itself by including
IDEAL mathematical references.

Regards,
geoff [GVA]
