Resamples input signal x according to time using an FIR filter implementation. Wire data to the x input to determine the instance to use.

datatype_icon

x

The input signal for resampling. The sampling interval of x is 1.

datatype_icon

time

Time instances for resampling in ascending order.

datatype_icon

error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: no error

datatype_icon

FIR filter specifications

Minimum values this node needs to specify the FIR filter.

datatype_icon

alias rejection (dB)

Minimum attenuation level of signal components aliased after any resampling operation. If alias rejection (dB) is less than 48, this node will use 48 instead.

Default: 120

datatype_icon

normalized bandwidth

Fraction of the new sampling rate that is not attenuated.

Default: 0.4536

datatype_icon

reset?

Initialization of the internal states. The first time this node 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 node. 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.

Default: FALSE

datatype_icon

anti-aliasing?

A Boolean that determines whether the input signal undergoes lowpass filtering when LabVIEW downsamples the signal. If anti-aliasing? is TRUE, this node protects the resampled signal from aliasing. However, the computation requirements increase during resampling.

Default: TRUE

datatype_icon

y

Resampled signal.

datatype_icon

time stamps

Time instance for each sample of every resampled signal in y. The number of elements in time stamps is equal to the number of columns in y. The contents of the time input determine the contents of time stamps. As a result of the internal state of the resampling filter, time stamps might have additional data at the beginning of the array and might lose some data at the end of the array.

datatype_icon

error out

Error information. The node produces this output according to standard error behavior.
