Dear time-nuts
In case of interest, you may check our fresh conference preprints from
IEEE--UFFC International Frequency Control Symposium -- European Frequency
and Time Forum 2013, just finished:
1. Clock Composition by Wiener Filtering Illustrated on Two Atomic Clocks
- about clock ensembling using estimator
- advantages over PLL&FLL (+ case study)
- much simpler in LTI case over currently used Kalman filters
2. Programmable Delay Controller Allowing Frequency Synthesis and
Arbitrary Binary Waveform Generation
- controllable delay line within FPGA fabric
- likely novel enhancement, possibly allowing to replace DDSes etc.
- still unsure, if it may actually improve frequency control circuits and
become widespread, or remain a curiosity only...

Best regards,
