[time-nuts] GPSDO disciplining algorithms

Hi all,

Thanks for the interesting feedback everyone, and thanks Attila, for your specific references - some reading ahead.

In principle, I should be able to remember all the stochastic / standard control theory, but I'm sure I'll have to 're-remember' it.

An interesting point re 3 use-cases  and re the vast majority of commercial algorithms being made for telco purposes. Does that imply that 10MHz lab-instrument feed for frequency / timing etc would ideally have some different algorithms? A series of algorithms (or at least a series of parameters for the same algorithm) targeted at particular time horizons?

I have found these recent-ish docs if anyone else is interested...
