Discusses a diophantine synthesiser.Note Sotiriadis' work on diophantine numbers and frequency synthesis appears to be a rehash of an old Patent perhaps due to a lack of competent searching for prior art.This issue was discussed on the list some time ago, Bruce On Friday, 29 July 2016 6:31 AM, Attila Kinali <att...@kinali.ch> wrote: On Fri, 22 Jul 2016 08:19:43 +0000 (UTC) Bruce Griffiths <bruce.griffi...@xtra.co.nz> wrote: > No, the first one merely uses a pair of cascaded heterodyne PLLs > as shown on p3 of the manual. Ok. I tried to understand how this circuit works. While I can see how a small and precise frequency offset can be produced, I do not see how a small phase offset with fixed frequency can be produced. At least not at the 100fs resolution level they are claiming in the manual. Would someone be so kind and explain the working of the circuit? > A diophantine setup may be useful here if one wished to construct something > similar. What is a diophantine setup?
