Minimal Synthesis of Two-Variable Reactance Matrices*
T.N. Chandrashekar Rao · Bell System Technical Journal · 1969
A simple algebraic method stemming from ideas in minimal state-variable realization theory is developed for the synthesis of two-variable reactance matrices. The method rests mainly on the factorization of a one variable polynomial matrix which is para-Hermitian and positive semidefinite on the imaginary axis, and always yields a realization minimal in both variables.
