Jury’s Stability Criterion<br />
The stability criterion by the Jury’s Stability Test: For the<br />
polynomial P(z) to have no roots on and outside the unit circle<br />
in the z-plane (i.e. for the digital or discrete data system to be<br />
stable), the following conditions must be satisfied:<br />
a) P(z)| z=1 = P(1) > 0 (13)<br />
{ > 0 for n even<br />
b) P(z)| z=−1 = P(−1)<br />
< 0 for n odd<br />
(14)<br />
