Cosmetic Stuff

Thanks to All of you for the help J

Now I am into the cosmetic stuff (= just about done) .

With a sample rate of ~90KHz the FFT frequency axis starts at 0 and goes
to
~45KHz.

I have a band pass filter from 35KHz to 55KHz.

Does anyone know how to make the frequency axis start at say 25KHz to
60KHz
?

Still a 45KHz spread, just off set by 25KHz so that 40KHz is roughly
centered .

It doesn’t REALLY matter, it just look better J

Thanks

Well, if you’re real-mode sampling, the highest frequency you can deal
with is 45KHz. Nyquist, not just a good idea, it’s a theorem :slight_smile:
