Re: [Matplotlib-users] PSD amplitudes
is the suggestion that the matplotlib algorithm is correct in computing
PSD amplitudes?
btw, increasing nFFT increases the number of points used in the FFT, which
increases the spectral frequency resolution (smaller binwidth) bu

Re: [Matplotlib-users] PSD amplitudes
Shouldn't the PSD for a simple sine wave tend to infinity
the spectral resolution will impact the amplitude, if you
are not dealing with a density. by definition a spectral density
has applied the bandwidth resolution correction. the PSD ampli

Please try the attached script.
The answer should be ~0 dB for each of the frequencies.
Most likely a simple scaling issue/parameter of which i'm ignorant.
