Jury's Stability Criteria / Algorithm
Jury's stability algorithm says
1. Form the first rows of the table by writing the coefficients of D(z).
JURY'S STABILITY CRITERIA /
ALGORITHM:
Jury's
stability algorithm says
1. Form
the first rows of the table by writing the coefficients of D(z).
2. Form
third and fourth rows of the table by evaluating the determinant CJ
3. This
process will continue until you obtain 2N-3 rows with last two having 3
elements. Y0,Y1,Y2
A digital
filter with a system function H(z) is stable, if and only if it passes the
following terms.
a. D(Z)|Z=1
> 0
b. (-1)N
D(Z)|Z=-1 >0
c. |b0|>|bN|,
|C0|
