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

Inputs/Outputs

  • cbool.png reset —

    reset resets the phase to the phase control value and the time stamp to zero. The default is FALSE.

  • cmsdt.png waveform in —

    waveform in is a waveform to align.

  • c1dmsdt.png waveforms in —

    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.

  • imsdt.png aligned waveform out —

    aligned waveform out contains an aligned waveform.

  • i1dmsdt.png aligned waveforms out —

    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.
