Group Delays of Thiran Allpass Interpolators
Figure ![[*]](../icons/crossref.png){kind=icon}
shows a family of
group-delay curves for Thiran allpass interpolators, for orders 1, 2,
3, 5, 10, and 20. The desired group delay was equal to the order plus
0.3 samples (which is in the ``easy zone'' for an allpass
interpolator).
