Robert Jördens 315338fca9 test/sawg: test HBF overshoot, fix sim patching 2017-06-12 20:35:47 +02:00
Robert Jördens 9a8a7b9102 sawg: handle clipping interpolator 
* give 1 bit headroom to interpolator to handle overshoot
* fix Config limiter widths (NFC)
* move clipper to behind the HBF to correctly shield DUC

This leaves a factor of two headroom for the sum of the following
effects:

  * HBF overshoot (~15 % of the step)
  * A1/A2 DDS sum

While this is technically not sufficient and can still lead to
overflows, it is unlikely that one would trigger those. It would require
doing large amplitude A1, large amplitude A2 and additionally doing
amplitude/phase jumps that would overshoot the HBF. No sane person would
try that, right?

closes #743

Robert Jördens 1fb3995ffc Revert "fir/ParallelHBFUpsampler: add headroom (gain=2)" 
This reverts commit 6ac9d0c41e.

Overshooting behavior must to be handled outside the FIR.

This currently breaks badly on UTF-8, and doesn't even return
a value of a correct type.
