I was given a project that uses a 150 some point interpolation filter that
upsamples digitized signal by 4. The digitized signals are sampled at rate
of 6.4 uS. I do not know the band checking characteristics of the filter,
only thing I know by looking at the code is that it upsamples by 4. No other
document.
One of my tasks is to have sample rate changed to 12.8 uS. Obviously, the
interpolation filter has to be changed -- I still want the same frequency
response and the same upsample factor.
How should I go about doing this conversion? Are there any free utilities I
can use to do a filter conversion? Any web based material I can use to
educate myself on generating interpolation filters?
Thanks!
