Thanks for your explanation. This makes a lot of sense. A carrier signal is generated (as high as 10^27) [1] - modulated by some observable - and then recorded

Thanks for your explanation. This makes a lot of sense. A carrier signal is generated (as high as 10^27) [1] - modulated by some observable - and then recorded and analyzed. The highest resolution event that will be visible in the waveform will be 1/(2f) where f is the frequency of the carrier signal. The 1/2 factor is due to the sampling theorem [2].
