FIR Narrowband Filtering (G Dataflow)

Input signal.

This input accepts the following data types:

• 1D array of double-precision, floating-point numbers
• 1D array of complex double-precision, floating-point numbers
• Waveform
• Waveform in complex double-precision, floating-point numbers
• 1D array of waveforms
• 1D array of waveforms in complex double-precision, floating-point numbers

The IFIR filter.

filter type

Passband of the filter.

Name	Description
Lowpass	Uses a lowpass filter.
Highpass	Uses a highpass filter.
Bandpass	Uses a bandpass filter.
Bandstop	Uses a bandstop filter.

Default: Lowpass

interpolation

Interpolation factor.

The model filter is stretched by interpolation times.

model filter

Coefficients of the model filter.

image suppressor

Coefficients of the filter image suppressor.

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error
If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

Filtered signal.

This output can return the following data types:

• Waveform
• Waveform in complex double-precision, floating-point numbers
• 1D array of waveforms
• 1D array of waveforms in complex double-precision, floating-point numbers
