Hello,

I have a data set which satisfies the Nyquist-Shannon theorem and would 
like to know the error of its phase. As I understand it, the phase error 
only depends on the signal-to-noise ratio of my data set provided there 
are enough samples (which is the case). However, I have not found any 
literature online or in my library which explains to me how to get the 
error from the SN ratio.

Thank you.

phase error distribution is indicated.The correction result is that the 
phase estimation error is reduced by analysing a windowing signal with 
Fourier transform, the leakage-induced phase error is investigated, and 
the phase error distribution is indicated.
