Web27 feb. 2014 · Gives you the rms value of the signal (in the time domain) as y. Multiplying y by 1.414 gives you the signal amplitude (with a decimal error for rounding sqrt (2) ). So in short I think your confusion comes from the plot being in the frequency domain and the RMS value being in the time domain. Web27 mei 2014 · RMS = sqrt (mean (x.^2)); The total energy of a signal is preserved under the Fourier transform ( Parseval's theorem ), so the sum (or integral) of the square of a function is equal to the sum (or integral) of the square of its transform. The RMS would be the square root of that value. My pleasure! Sign in to comment. More Answers (2) foot heaven massage cedar park

As dpb said, it is impossible to know if some arbitrary value for RMSE is good or bad. Only you know if it is good, because only you can know how much noise you would expect in the data.
