Inputs/Outputs

  • cerrcodeclst.png error in (no error) —

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

  • cmsdt.png Signal —

    Specifies the block diagram terminal of the signal you want to load. This input is available only if you select the From terminal option in the Data Source section.

  • c1ddbl.png real signal —

    Specifies the input signal. The signal can be a waveform, a real array, or a complex array.

  • cpath.png File path —

    Specifies the file path of the data you want to load. This input is available only when you select the From file option in the Data Source section.

  • c1dcdb.png complex signal —

    Specifies the input signal. The signal can be a waveform, a real array, or a complex array.

  • imsdt.png Denoised Signal —

    Returns the estimated signal after denoising.

  • ierrcodeclst.png error out —

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

  • i1ddbl.png real denoised —

    Contains the estimated signal after de-noising.

  • i1dcdb.png complex denoised —

    Contains the estimated signal after de-noising.
