    $\begingroup$ @Hilmar Have you read this paper? citeseerx.ist.psu.edu/viewdoc/… I had a similar problem with ultrasounds and this paper convinced me and my former employer to replace FIR filters by IIR filters. $\endgroup$ Commented Dec 2, 2021 at 19:50

  • $\begingroup$ @Hilmar: Concerning your example, the pole radii of the IIR high-pass filter are between $0.995$ and $0.999$; wouldn't that be a nightmare to implement? $\endgroup$ Commented Dec 4, 2021 at 15:19

    $\begingroup$ For anyone who in the future wants to access @Ben's link, it can now be found here. The paper is called "A New Perspective on Decimation and Interpolation Filters" by Steve Green at Cirrus Logic, Inc. For what it's worth, you can fix citeseerx links by following the procedure here $\endgroup$ Commented Nov 11 at 18:59
