Owning Palette: Filters VIs

Use the Advanced FIR Filtering VIs to implement advanced FIR filters.

Note  The Convolution VI is available on both the Advanced FIR Filtering palette and the Signal Operation palette because you can use the VI for both filtering and signal manipulation.

The VIs on this palette can return signal processing error codes.

Palette Object	Description
Convolution	Computes the convolution of the input sequences X and Y. The data type you wire to the X input determines the polymorphic instance to use.
FIR Filter	Filters the input sequence X using the direct-form FIR filter specified by FIR Coefficients. The data type you wire to the X input determines the polymorphic instance to use.
FIR Narrowband Coefficients	Generates a set of filter coefficients to implement a digital interpolated FIR (IFIR) filter.
FIR Narrowband Filter	Filters the input sequence X using the interpolated FIR (IFIR) filter specified by IFIR Coefficients.
FIR Windowed Coefficients	Generates the set of filter coefficients you need to implement an FIR windowed filter.
IIR Filter with I.C.	Filters the input sequence X using the direct form IIR filter specified by Reverse Coefficients and Forward Coefficients. You can use this VI to process blocks of continuous data.
IIR Filter	Filters the input sequence X using the direct form IIR filter specified by Reverse Coefficients and Forward Coefficients. The data type you wire to the X input determines the polymorphic instance to use.
Parks-McClellan	Generates a set of linear-phase FIR multiband digital filter coefficients using the # of taps, sampling frequency: fs, Band Parameters, and filter type.
Savitzky-Golay Filter Coefficients	Designs a Savitzky-Golay FIR smoothing filter. This VI returns the designed Savitzky-Golay filter coefficients and the differentiation filter coefficients.
