Inputs/Outputs

  • cigrn.png reference of TF coefficients indicator

    reference of TF coefficients indicator specifies the reference of TF coefficients indicator. If you do not wire this input, this VI does not set the scale information and color table information for TF coefficients indicator.

  • cbool.png dB on? (F)

    dB on? specifies whether to display the magnitude of TF coefficients in decibels. The default is FALSE.

  • c2dcdb.png TF coefficients

    TF coefficients specifies the linear time-frequency representation of the signal. You can wire the STFT coef output of the TFA STFT VI or the Gabor coef output of the TFA Discrete Gabor Transform VI to TF coefficients.

  • cfxdt.png scale info

    scale info specifies the time scale information and the frequency scale information of the time-frequency representation.

  • cerrcodeclst.png error in (no error)

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

  • cu16.png color table

    color table specifies the color table of TF coefficients indicator.

  • cu16.png display type

    display type specifies to display the magnitude or phase of the coefficients in the TFA Coefficients Indicator.

  • i2ddbl.png TF coefficients indicator

    TF coefficients indicator returns the magnitude or phase of TF coefficients according to display type on an intensity graph. The x-axis represents time, and the y-axis represents frequency. The color indicates the magnitude or phase of TF coefficients.

  • ierrcodeclst.png error out

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