#33 closed defect (wontfix)

SIFO and MOMS filter incompatibilities (filter length)

Description

The lengths of the FIR filters SIFO is using have to be the same. Works when adding 6-tap MOMS to the 6-tap SIFO filter set. Adding 4-tap or 6-tap MOMS to the 12-tap SIFO filter sets is conflicting.

Replying to benjamin.bross@…:

From my understanding, there is no agreement to use the same FIR filter length in SIFO. Maybe the more reasonable way is to choose filters based on the number of operations, however, I am not sure how we can map the number of operations of frame-based IIR stage of MOMS to the block-based one as in other filters. In my personal opinion, consideration of FIR stage only is conflicting.
