ippStsIIRPassbandRippleErr
Chebyshev type I IIR design uses passband ripple as a design constraint. This status points to the filter-design parameters, not to the input samples that will later be filtered.
Check the ripple value before coefficients are generated. A zero or negative ripple changes the design problem, while excessively large ripple can make the requested response unusable.
Check these details
- The ripple value passed to the IIR design routine.
- Whether the caller mixes linear amplitude and decibel-style interpretation.
- The filter order and cutoff frequency used with the same design call.
