Exact solution of CP is returned by pure sines, the responses of conservative systems.
- class="label">•
CP is generally to be interpreted as separating the least dispersive components.
- class="label">•
CP may be generalized to arbitrary sets of filters.
- class="label">•
A generalization of CP is given based on optimized filters and joint diagonalization.
- class="label">•
Generalized CP includes several other BSS algorithms as particular cases.
