[QUOTE="person123, post: 6207471, member: 611120"] When I started this thread I did not. However, I ended up asking my graduate mentor this question, and I believe his answer directly relates to your question. He said the equation was the following: $$PSD=Y Y^* L \Delta t$$ ##Y## is the Fourier Transform, ##L## is the sample length, and ##\Delta t## is the sample rate. He also said that the units of the Fourier Series itself (for pressure say) would simply be ##Pa##. Therefore, the PSD would be ##Pa^2/Hz## I believe. This is what I used in my code. I still don't really have a true understanding of why you do this, but I think my understanding is good enough to create functions based on this. If you or anyone else could give me (or refer me to) an intuitive understanding of how this relates to power, I would greatly appreciate it. [/QUOTE]
