What is a power spectrum?

An animation showing the transformation of a time series into a power spectrum.

this dude uploaded one epic video and disappeared

Now THIS is how you make an informative video. Straightforward, very clear, and makes great use of animations!

If heaven actually exists and you need to justify your entry, play them this video.

An amazing video! I was looking for something exactly like this! How did you make this animation?

Great!
Then what would be the power spectral density?
Thank you.

What I can't figure is how this type of spectra is measured in a turbulent flow, This spectra is for a single point? If so, is this spectra representative of the whole flow turbulence?

It looks a simple Fourier Spectrum. Why do you call it "Power" Spectrum?

Whats the difference of power and fft method? This extraction is same as fft result

[wafahabib]

Hi. Is power spectrum the same as spatial analysis or spectral analysis?

How can I know the sin waves that composite the signal? please answer me
