Help¶

This option enables the Filtering Functions, which support the
following operations:

* Convolution
* Partial Convolution
* Correlation

The following filter types are supported:

* FIR (finite impulse response) Filter
* FIR Lattice Filter
* FIR Sparse Filter
* FIR Filter with Decimator
* FIR Filter with Interpolator
* IIR (infinite impulse response) Lattice Filter
* Biquad Cascade IIR Filter, Direct Form I Structure
* Biquad Cascade IIR Filter, Direct Form II Transposed Structure
* High Precision Q31 Biquad Cascade Filter
* LMS (least mean square) Filter
* Normalized LMS Filter
