Resample (constant to constant, complex single-channel) VI
- Updated2025-07-30

Resamples input signal X according to delay and dt using an FIR filter implementation. Wire data to the X input to determine the polymorphic instance to use or manually select the instance.

Inputs/Outputs
anti-aliasing?
—
anti-aliasing? specifies whether the input signal undergoes lowpass filtering when LabVIEW downsamples the signal. If anti-aliasing? is TRUE (default), this VI protects the resampled signal from aliasing. However, the computation requirements increase during resampling.
reset?
—
reset? controls the initialization of the internal states. The default is FALSE. The first time this VI runs or when reset? is TRUE, LabVIEW initializes the internal states to zero. When reset? is FALSE, LabVIEW initializes the internal states to the final states from the previous call to this instance of this VI. To process a large data sequence consisting of smaller blocks, set this control to TRUE for the first block and to FALSE for continuous filtering of all remaining blocks.
X
—
X contains the complex input signal for resampling. The sampling interval of X is 1.
delay
—
delay specifies the timestamp for Y.
dt
—
dt specifies the sampling interval for Y.
error in (no error)
—
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
FIR filter specifications
—
FIR filter specifications specifies the minimum values this VI needs to specify the FIR filter.
Y
—
Y returns the complex resampled signal.
t0
—
t0 returns the time instance for the first sample in Y.
error out
—
error out contains error information. This output provides standard error out functionality. |
