| Jan 9, 2012 at 16:29 | comment | added | zetah | OK, thanks. I'll range filter at fixed rates by hand. I took a look at pointed answer... maybe I'll open my workbook and do some math, but I doubt my skills ;) | |

The results can be messy: see, for example, this answer which describes the calculations needed for a very simple filter. | |
| Jan 9, 2012 at 16:07 | comment | added | zetah | But I want passband at 1-2 KHz at arbitrary sample rate. I made quick calculations and it seems like coefficients from some filter parts are correlated, but not all. So do I need to reshape filters for fixed sample rates, or there is hope in quest for function/approach that calculates this coefficient for arbitrary sample rate? | |
