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
I have a band pass filter from 35KHz to 55KHz.
Does anyone know how to make the frequency axis start at say 25KHz to
Still a 45KHz spread, just off set by 25KHz so that 40KHz is roughly
It doesn’t REALLY matter, it just look better J
