Re: Measuring noise levels

You're in the right direction. This digitally mimics (sort of) what a
true rms meter does in the analog domain. One needs to be a little
careful. Your 1024 samples relates to a certain amount of time
(depending on sampling rate) and then the averaging of these groups
together will roughly correspond to a continuous rms with post filter.
We have an app note on line somewhere at analog.com on rms
measurement.
