Computes the energy distribution of the input signal in the joint time-frequency domain using the Wigner-Ville distribution (WVD) algorithm.
The input time-domain signal.
Time intervals, in units of samples, of the Wigner-Ville Distribution (WVD).
Increasing time increment decreases the computation time and reduces memory requirements but also reduces time-domain resolution. Decreasing time increment improves time-domain resolution but increases the computation time and memory requirements.
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
The energy distribution of the input signal in the joint time-frequency domain.
Error information. The node produces this output according to standard error behavior.
For a discrete signal X, with an analytic associate of Z, the following equation defines the Wigner-Ville Distribution (WVD) of the analytic associate, :
