ippStsFIRGenOrderErr
An FIR generator order controls how many taps the designed finite impulse response can use. Too small an order cannot represent the requested response, and a nonsensical order prevents coefficient generation.
Diagnose the design stage first: the tap count, symmetry assumptions and window choice must be valid before convolution or streaming state is examined.
Check these details
- The order/tap-count argument and whether it is inclusive or exclusive.
- Window type and cutoff parameters used in the same design call.
- Any caller-side conversion from user-visible filter length to IPP order.
