Owning Palette: Adaptive Filters VIs
Requires: Adaptive Filter Toolkit
Creates a finite impulse response (FIR) adaptive filter with the sign least mean squares (LMS) algorithm.
|Note National Instruments recommends that you create and destroy adaptive filters outside loop structures.|
|filter length specifies the filter length of the adaptive filter. The value must be greater than or equal to 2. The default is 128.|
|step size specifies the step size of the adaptive filter. The value must be greater than zero. A large step size can improve the convergence speed of the resulting adaptive filter. However, a large step size might result in a large steady state error or cause instability in the resulting adaptive filter. The default is 0.01.|
|sign type specifies the type of sign LMS algorithm this VI uses to create the adaptive filter.
|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 that this VI creates.|
|error out contains error information. This output provides standard error out functionality.|
