Robert Jordens 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		2017-06-12 20:33:54 +02:00
