Owning Palette: Time Frequency Analysis VIs

Requires: Advanced Signal Processing Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Utilities VIs to generate signals for demonstration purposes or to access scale information in the time-frequency representation.

The VIs on this palette can return general LabVIEW error codes or specific Time Frequency Analysis error codes.

Palette ObjectDescription
TFA Configure Coefficients IndicatorDisplays the magnitude or phase of the linear time-frequency coefficients of a signal on an intensity graph.
TFA Configure Spectrogram IndicatorDisplays the spectrogram of a signal on an intensity graph. Wire data to the color table input to determine the polymorphic instance to use or manually select the instance.
TFA Data SamplesContains the demonstration data samples for the Time Frequency Analysis VIs.
TFA Gaussian Chirp GeneratorGenerates a summation of Gaussian chirps with different parameters.
TFA Get Time and Freq Scale InfoGets the time scale information and the frequency scale information of the time-frequency representation.
TFA Read from FileReads data from a spreadsheet text file that contains a 1D array, a 2D array, a byte stream file of single-precision numbers, a byte stream file of 16-bit signed integers, a file created with the Write Waveforms to File VI, a WAV file, a JPG file, a BMP file, or a PNG file.
TFA Set Time and Freq Scale InfoSets the time scale information and the frequency scale information for the time-frequency representation.
