Hi,
I am currently looking into a low pass filter with very small propagation delay. I designed a Butterworth filter in matlab and I have attached the step response to this thread. Matlab indicate that the settling time is about 19us. I drew a line at 19us and then traced it back to where the amplitude match the final amplitude at settling time.
Is there any reason I cannot wait only the 4us and sample the output there. Does that amplitude point changes based on freq or start and end amplitude of filter input. Any insight would be highly appreciated
