The reason I talked about using the 500 sample rate (in the post about anti-alias filters) is because I could not find another way to limit the frequency range of the spectral “analysis” plot to show only the low frequency end in order to peruse the 0 to 20 Hz range
… is there another way of limiting the range of the spectral plot to say, 0 to 100 Hz without re-sampling? It doesn’t really matter that much as the re-sampled plots are good enough since there is not much high frequency noise in what I am recording, but it would be a good option to have.
Thanks very much
