Re: [time-nuts] DMTD Systems Papers
Hi Depending on just what sort of DMTD you are after, there are an enormous number of JPL reports on their system. They range from papers that are basically operating manuals (when this happens that shows up on the screen) to deep dives on obscure math. If you are not after a 100 Hz system they may be of limited use. If you are getting into building one, things like the Collins paper on hard limiters would be of use.

Re: [time-nuts] DMTD Systems Papers
NIST Technical Note 1337: Characterization of Clocks and Oscillators. It's basically a Time-Nuts Textbook that includes some of the papers you mention as well as many others. 1990 - 22MB - 357 pages. http://tf.boulder.nist.gov/general/pdf/868.pdf The NIST Time Frequency Publication Database is a great place to browse for Time-Nuts treasures (no suprise there!). It took me a while to figure out that to browse the list you just submit an empty search. http://www.tf.nist.gov/timefreq/general/publications.htm Ed Brian Kirby wrote: Here's a list of papers I have found on DMTD system designs that have some inside details.
