Coupling matrix of a 10th-order dual-mode asymmetric canonical filter.

This paper deals with a simple method to extract the coupling matrix of a 10th-order dual-mode asymmetric canonical filter. The coupling matrix of an asymmetric canonical filter is obtained by applying a plane rotation technique to the coupling matrix of a symmetric canonical filter. This paper gives a list of pivots and rotation angles to obtain the coupling matrix of an asymmetric canonical-structure filter. © 2003 Wiley Periodicals, Inc.
