ippStsTrnglFreqErr
A triangle wave is still a sampled periodic signal, so its frequency must satisfy the normalized digital-frequency range accepted by the routine.
If the value came from Hz, verify the sample rate and normalization before suspecting output-buffer layout.
Check these details for ippStsTrnglFreqErr
- Hz-to-normalized-frequency conversion.
- Nyquist boundary conditions.
- Frequency changes during streaming.
