Ec. Tan, DERIVATION OF SIMILAR MATRIX OF THE SCATTERING MATRIX FOR NUMERICAL COMPUTATION IN ELECTRONIC NETWORKS, Journal of circuits, systems, and computers, 6(6), 1996, pp. 599-606
The companion-form system matrix of an electronic network may be incon
venient or inappropriate for certain applications. In pole computation
s, it may produce values which are less accurate at certain points in
the s-plane. In the state-space analysis, it is not a very suitable fo
rm for input/output computations especially in large system networks w
here iterative methods are used. The paper presents the derivation of
a similar matrix that is in a more desirable form under the above-ment
ioned circumstances. Some examples are also given to illustrate the de
rivation process.
