Filters an input sequence using the interpolated FIR (IFIR) filter specified by a set of coefficients.

Programming Patterns

You can use FIR Narrowband Coefficients to generate the IFIR Coefficients for this node.

connector_pane_image
datatype_icon

x

The input signal to filter.

Default: Empty array

datatype_icon

IFIR coefficients

The IFIR coefficients that define the filter.

datatype_icon

filter type

The filter type that you want to use to filter the data.

Lowpass

Uses a lowpass filter.

Highpass

Uses a highpass filter.

Bandpass

Uses a bandpass filter.

Bandstop

Uses a bandstop filter.

Wideband-Lowpass

Uses a wideband-lowpass filter with cutoff frequencies near Nyquist.

Wideband-Highpass

Uses a wideband-highpass filter with cutoff frequencies near zero.

Default: Lowpass

datatype_icon

interpolation

The interpolation factor M. The model filter in this is stretched by interpolation times.

datatype_icon

Model Filter

The coefficients of the model filter.

datatype_icon

Image Suppressor

The coefficients of the filter image suppressor.

datatype_icon

filtered x

An array of filtered samples.

datatype_icon

error

A value that represents any error or warning that occurs when this node executes.
