Performs element-wise alignment of two waveforms and returns the aligned waveforms. The data types you wire to the waveform inputs determine the polymorphic instance to use.

Inputs/Outputs

  • cu16.png exported interval —

    exported interval defines the time stamp of the waveform outputs.

    0Common (default)
    1Global
  • cbool.png open interval? (T) —

    open interval? defines the interval over which the input waveform extends. The default is TRUE, which selects an open interval.

    For example, assume an input waveform contains 3 data elements at t = {0, dt, 2dt}. An open interval defines the waveform as extending over the time interval 0 ≤ t < 2dt, and a closed interval defines the waveform as extending over the time interval 0 ≤ t < 3dt.

  • c1dmsdt.png M waveforms in —

    M waveforms in is an array of waveforms to align.

  • c1dmsdt.png N waveforms in —

    N waveforms in is an array of waveforms to align.

  • cu16.png interpolation mode —

    interpolation mode specifies the interpolation method.

    0Coerce—Each output sample is set equal to the input sample value that is closest to it in time.
    1Linear (default)—Each output sample value is a linear interpolation between the two input samples that are closest to it in time.
    2Spline—Uses the spline interpolation algorithm to compute the resampled values.
    3FIR filter—Uses a finite impulse response (FIR) filtering algorithm to compute the resampled values.
  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • cnclst.png FIR filter specifications —

    FIR filter specifications specifies the minimum values this VI needs to specify the FIR filter.

  • cdbl.png alias rejection (dB) —

    alias rejection (dB) specifies the minimum attenuation level of signal components aliased after any resampling operation. The default is 120.

  • cdbl.png normalized bandwidth —

    normalized bandwidth specifies the fraction of the new sampling rate that is not attenuated. The default is 0.4536.

  • cbool.png interpolation —

    interpolation specifies whether interpolation is performed. The default is TRUE.

  • i1dmsdt.png M aligned waveforms out —

    M aligned waveforms out is an array of aligned waveforms.

  • i1dmsdt.png N aligned waveforms out —

    N aligned waveforms out is an array of aligned waveforms.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
