Owning Palette: Filter Design VIs

Use the Special Filter Design VIs to create notch peak, infinite impulse response (IIR) comb, maximally flat, narrowband, and other special filters.

The VIs on this palette can return general LabVIEW error codes or specific digital filter design error codes.

Palette Object	Description
DFD Arbitrary Group Delay Design	Creates an allpass filter with a group delay that you specify.
DFD Group Delay Compensator	Compensates the group delay of a filter.
DFD IIR Comb Design	Creates an infinite impulse response (IIR) comb filter. You must manually select the polymorphic instance you want to use.
DFD IIR Notch Peak Design	Designs a notch or peak filter in which the notch or peak is located at the center frequency. You must manually select the polymorphic instance you want to use.
DFD Maxflat Design	Creates a lowpass finite impulse response (FIR) or infinite impulse response (IIR) filter with a magnitude frequency response that is maximally flat at 0 and at half the sampling frequency.
DFD Narrowband Filter Design	Creates a narrowband filter using the interpolated finite impulse response (FIR) technique.
