TFA Cone-Shaped Distribution Details

CSD is a type of Cohen's class distribution and is the smooth version of the Wigner-Ville Distribution (WVD). CSD has better readability than WVD but worse time-frequency resolution, because CSD suppresses the cross-term interference between two signal components that have a large difference in central time or central frequency. However, CSD does not suppress the cross-term interference between two signal components that have the same central time. Therefore, for large values of the signal length, this VI requires a long computation time and more memory. National Instruments recommends that you limit signal to 15,000 samples.
