BodePlot strange result (Non Linear and Sample Rate Adapt)
Re: BodePlot strange result (Non Linear and Sample Rate Adap
I was using my frequency predictor a lot, to see how i could adapt some filter coefficients with different sample rate.. (and not so much for non linear think)
But there's a more easy way to measure this !
I must have think about it ! It's really more easy and fast.
In fact it's simply in the array section process, after Analyser and graph, we might do a 1/2 section of the array
to get frequency from 0 to 22050 hertz.
To get the same at a different sample rate we could just divide more.. At 88200 the section is 1/4 of the array.
Very very simple, but i only discover this now
Some little difference in this very simple filter even with my adaptation..
But i don't know if i need a better way to do or if it's some precision issue or limitation of filter at some sample rate...
