==========================================================
D-Flandrin Distribution of a Hyperbolic Group Delay Signal
==========================================================

This example shows the D-Flandrin distribution of a signal having hyperbolic
group delay. This is the only type of distribution that almost perfectly
localizes signals having a group delay in :math:`1 / \sqrt{\nu}`

Figure 4.22 from the tutorial.
