Displays the square magnitude or the phase of the wavelet coefficients on an intensity graph. This VI displays the square magnitude of the real-valued wavelet coefficients from the WA Continuous Wavelet Transform VI and displays the square magnitude or the phase of the complex-valued wavelet coefficients from the WA Analytic Wavelet Transform VI. Wire data to the CWT coef input or the AWT coef input to determine the polymorphic instance to use or manually select the instance.

Inputs/Outputs

  • cigrn.png reference of scalogram indicator —

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

  • cbool.png dB on? (F) —

    dB on? specifies to display the scalogram in decibels or in a linear scale. If dB on? is TRUE, this VI returns the scalogram in decibels. If dB on? is FALSE, this VI returns the scalogram in a linear scale. The default is FALSE.

  • c2ddbl.png CWT coef —

    CWT coef specifies the results of the continuous wavelet transform (CWT).

  • cfxdt.png scale info —

    scale info specifies the time information and the scale (frequency) information of CWT coef.

  • cbool.png ignore timestamp? (F) —

    ignore timestamp? specifies whether this VI forces the timestamp of the input signal to 0 so you can define the limit signals relative to the beginning of the input signal. The default is FALSE, which means this VI uses the timestamp in scale info.

  • cerrcodeclst.png error in (no error) —

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

  • c1du32.png color table —

    color table specifies a 256-element array of colors that defines the color table of scalogram indicator.

  • i2ddbl.png scalogram indicator —

    scalogram indicator displays the scalogram on an intensity graph. The x-axis represents time, and the y-axis represents the scale, or the frequency. The color indicates the square magnitude or the phase of the signal.

  • ierrcodeclst.png error out —

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