[time-nuts] Phase shifter circuit for DTMD

2009-07-24 Thread Stephan Sandenbergh
Hi, Many sources and papers refer to the actual DMTD mixer system (and zero-crossing detector etc.). But, I've seen very little on the phase shifter circuits, that are used in conjunction with this system. I was hoping some of you might have experience, and perhaps a circuit example. If it is simi

Hi, Thanks for the replies. I agree. One is interested in the timing of beat notes. But, I'm slightly confused now. It might be a language problem on my side. Quoting Howe, Allan and Barnes, 1981, "...adjust the phase so that the two beat frequencies are nominally in phase; this adjustment sets u
