Owning Palette: Adaptive Filters VIs

Requires: Adaptive Filter Toolkit

Retrieves the filter coefficients from an adaptive filter that you create with the least mean squares (LMS) or recursive least squares (RLS) algorithms. You must manually select the polymorphic instance you want to use.

Note  You can use the AFT Set Coefficients VI to set the coefficients of an adaptive filter.

Examples

Use the pull-down menu to select an instance of this VI.

AFT Get Coefficients (FIR, Real)

adaptive filter in specifies the adaptive filter from which you want to retrieve the filter coefficients.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
adaptive filter out returns the adaptive filter in unchanged.
coefficients returns the coefficients of the adaptive filter.
error out contains error information. This output provides standard error out functionality.

AFT Get Coefficients (FIR, Complex)

adaptive filter in specifies the adaptive filter from which you want to retrieve the filter coefficients.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
adaptive filter out returns the adaptive filter in unchanged.
coefficients returns the coefficients of the adaptive filter.
error out contains error information. This output provides standard error out functionality.

Examples

Refer to the following VIs for examples of using the AFT Get Coefficients VI:
