=============================================
Wigner-Ville Distribution of a Doppler Signal
=============================================

This example shows the Wigner-Ville distribution of a Doppler signal. The
signal steadily rises and falls, but there are many interference terms present
in the time-friequency plane, due to the bilinearity of the signal.

Figure 4.2 from the tutorial.
