Hello, I wrote a matlab code to find the PSD (Power Spectral Density) of a signal, but my amplitude for frequency is in dB/Hz. I am trying to compare my results to some data of another lab that has amplitude in pm^2/Hz. Would anyone be able to help me how to convert this value for PSD?
Thanks,

I am not certain what the units of ‘pm’ are. To convert dB (as power) to amplitude, this little anonymous function works:
dB2amplitude = @(dB) 10.^(dB/20);
