Spectral factorization revisited |
If represents the limit of the series in (8),
Therefore, represents the causal or anticausal part of the given spectrum .
Table 3 summarizes the spectral factorization
relationships equivalent to those established for real numbers in
Table 1.
The convergence properties are similar to those derived for real numbers. As shown above, the Newton-Raphson method should have the fastest convergence.
