Resamples a signal according to specific delay and sampling interval.
A Boolean that specifies the initialization of the internal state of the node.
True | Initializes the internal state to zero. |
False | Initializes the internal state to the final state from the previous call of this node. |
This node automatically initializes the internal state to zero on the first call and runs continuously until this input is True.
Default: False
Sampling interval, in seconds, between data points in the resampled signal.
Default: 1
Start time value for the resampled signal.
This input is available only if you wire a waveform or an array of waveforms to signal.
Timestamp for resampled signal.
This input is available only if you wire one of the following data types to signal:
Default: 0
Algorithm this node uses to resample the input signal.
Name | Value | Description |
---|---|---|
coerce | 0 | This node sets each output sample value to the input sample value that is closest to it in time. |
linear | 1 | This node sets each output sample value to the linear interpolation between the two input samples that are closest to it in time. |
spline | 2 | This node uses the spline interpolation algorithm to compute the resampled values. |
FIR filter | 3 | This node uses a finite impulse response (FIR) filtering algorithm to compute the resampled values. |
Default: FIR filter
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.
Default: No error
Minimum values this node needs to define the FIR filter.
This input is valid only when you set interpolation mode to FIR filter.
Minimum attenuation level of signal components aliased after any resampling operation.
If alias rejection (dB) is less than 48, this node uses 48 instead.
Default: 120
Fraction of the new sampling rate that is not attenuated.
Default: 0.4536
A Boolean that determines whether the input signal undergoes lowpass filtering when this node downsamples the signal.
True | This node protects the resampled signal from aliasing. The computation requirements increase during resampling. |
False | The input signal undergoes lowpass filtering when this node downsamples the signal. |
Default: True
Actual start time of the resampled signal.
This output is available only if you wire a waveform or an array of waveforms to signal.
Start time of the next resampled signal.
This output is available only if you wire a waveform or an array of waveforms to signal.
Error information.
The node produces this output according to standard error behavior.

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.
A Boolean that indicates whether the actual start time of the resampled signal equals the start time value you specified.
True | The actual start time of the resampled signal does not equal the start time value you specified. |
False | The actual start time of the resampled signal equals the start time value you specified. |
This output is available only if you wire a waveform or an array of waveforms to signal.
