From my understanding, the sampling frequency is the inverse distance between data points. Is this correct, or do I have to use something else? Maybe an example can make my question a bit clearer. If I want to plot the fft spectrum what option would be correct? sample_rate_1, sample_rate_2,or s…

[image] feanor12: the sampling frequency is the inverse distance between data points. Yes.

What is the fftfreq sampling frequency?

Yes.
