If one creates a 1V RMS sine wave, e.g. with a peak value of 1.414 or
peak-peak of 2.83, then computes psd, the resulting amplitude is around
24 dB, yet classic theory dictates the answer ought to be 20 log(1) = 0
dB.
This offset seems consistent across various frequencies/sample
rates/amplitudes.
Can someone illuminate the amplitude scaling of the psd algorithm?
Thanks.
