Dear John Smith,
I do not know the free programs and I think it are not present. The
processing of a signal must be carried out by the microprocessor.
Proton frequency are measured by counter of quartz pulses for each
period by transitions of a signal through zero. The duration of
periods summarize definitely way. I know unique (sole) not Russian
article where this idea is stated. It is "Farrel E.J., Grosch C.B.
Determination of period from times of zeros // Proceedings of IEEE,
1965, V.12, N12, p. 2162-2163". May be it be useful for you. I shall
be grateful for the information if you or anyone will find others
article and send me.
Best regards
Vladimir Sapunov

This is very interesting Vladimir,
Welcome to the group, you will find some funny ideas here :-)
Do you know of a ( free ) program for the digital processing of
the signal from a normal PPM ?

Dear Keith Barr!
I have come in protonmag forum yesterday and I was glad to
receive an interesting question at once. I am a professional
developer of Overhauser magnetometer. I want to ask what is
necessary for you? Really Overhauser sensorss have only smaller
dimensions and energy consumption. You can have sensitivity up
to 0,01nT at speed 3 seconds and energy 10 Wt with the ordinary
proton sensors if you will be use digital algorithms of
processing of a precession signal. Concerning to Overhauser
sensors, this are too simple sensors in principle but it is
necessary to have the special equipment and experience of works.

To any and all:
Is there anyone out there that's built an Overhauser mag?
I'd love to hear details.
