Version:
    Last Modified: March 15, 2017

    Performs single-shot element-wise alignment of waveforms and returns the aligned waveforms.

    connector_pane_image
    datatype_icon

    exported interval

    Timestamp of the waveform outputs.

    Name Value Description
    common 0 Uses common timestamp.
    global 1 Uses global timestamp.

    Default: common

    datatype_icon

    open interval?

    Interval over which the input waveform extends.

    True Uses an open interval.
    False Uses a closed interval.

    Default: True

    datatype_icon

    waveforms

    An array of waveforms to align.

    datatype_icon

    interpolation mode

    Algorithm this nodes uses to perform alignment of waveforms.

    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: linear

    datatype_icon

    error in

    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

    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.

    Default: 120

    datatype_icon

    normalized bandwidth

    Fraction of the new sampling rate that is not attenuated.

    Default: 0.4536

    datatype_icon

    interpolation?

    A Boolean that specifies whether this node performs interpolation.

    True Performs interpolation.
    False Does not perform interpolation.

    Default: True

    datatype_icon

    aligned waveforms

    Aligned waveforms.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
