Computes the duration of waveform in using the following equation: duration = (#samples-1) x dx. Wire data to the waveform in input to determine the polymorphic instance to use or manually select the instance.

Inputs/Outputs

  • 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.

  • cdigwdt.png waveform in —

    waveform in is the digital waveform for which you want the duration.

  • cerrcodeclst.png error in (no error) —

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

  • idigwdt.png waveform out —

    waveform out returns waveform in unchanged.

  • idbl.png duration —

    duration is the duration of the waveform.

  • ierrcodeclst.png error out —

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