Hi,

I sample a periodic signal with 8 fold oversampling with regard to the 
fundamental wave. I get less than 10Bit valid amplitude resolution. The 
jitter of the sample clock is unknown. I want to measure the phase of 
the fundamental with an accuracy in the range of 175e-6 radiant. I see 
all kind of strange effects I cannot explain, I am at least factor 10 
away from my target accuracy.

So my question: Could you give me some pointers to literature regarding 
this problem, esp. conversion of amplitude noise to phase noise and 
phase issues with ADCs.


Thank you

Cheers
