Use the Time Frequency Analysis VIs to transform a time-domain signal to a joint time-frequency domain representation. You can extract useful information from the time-frequency domain representation of a signal, or you can process a time-frequency domain representation and reconstruct a time-domain signal.
|Feature Extraction VIs||Use the Feature Extraction VIs to extract useful information from the quadratic time-frequency representation of signals.|
|Online JTFA VIs||Use the Online JTFA VIs to perform time-frequency type calculations continuously.|
|Time Frequency Spectrogram VIs||Use the Time Frequency Spectrogram VIs to compute the quadratic energy distribution of the signal in the joint time-frequency domain.|
|Time Frequency Transform VIs||Use the Time Frequency Transform VIs to decompose signals as linear combinations of elementary functions. The elementary functions are localized in time and frequency. You also can reconstruct the signal from the elementary functions.|
|Utilities VIs||Use the Utilities VIs to generate signals for demonstration purposes or to access scale information in the time-frequency representation.|
