ippStsFilterFrequencyErr
IPP filter-design routines usually express digital cutoff frequencies in normalized units. A value outside the valid normalized range means the requested filter cannot be mapped to the sampled signal.
This is a design-parameter error. Rechecking the source buffer will not help until the cutoff, sampling-rate conversion or normalization convention is fixed.
Check these details
- Normalize by the sampling frequency expected by the IPP routine.
- Ensure cutoff values are strictly inside the documented range.
- Keep passband and stopband frequencies ordered for multi-band designs.
