Owning Palette: Filter Design VIs

Requires: Digital Filter Design Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

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 ObjectDescription
DFD Arbitrary Group Delay DesignCreates an allpass filter with a group delay that you specify.
DFD Group Delay CompensatorCompensates the group delay of a filter.
DFD IIR Comb DesignCreates an infinite impulse response (IIR) comb filter. You must manually select the polymorphic instance you want to use.
DFD IIR Notch Peak DesignDesigns 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 DesignCreates 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 DesignCreates a narrowband filter using the interpolated finite impulse response (FIR) technique.
