| BiQuadChain & add | ( | BiQuad * | bq ) |
Add a BiQuad pointer to the list: bqc.add(&bq);.
- Parameters:
-
bq Pointer to BiQuad instance
- Returns:
- Pointer to BiQuadChain
Definition at line 103 of file BiQuad.cpp.
| std::vector< std::complex< double > > poles | ( | ) |
Return poles of the BiQuad filter.
- Returns:
- vector of std::complex poles
Definition at line 138 of file BiQuad.cpp.
| bool stable | ( | ) |
Is this biquad-chain stable? Checks if all poles lie within the unit-circle.
- Returns:
- boolean whether the chain is stable or not
Definition at line 146 of file BiQuad.cpp.
| double step | ( | double | x ) |
Execute a digital time step cascaded through all bq's.
- Parameters:
