• McMillan degree of G(s) = å deg(bi(s)) where deg(bi(s)) denotes
the degree of the polynomial bi(s).
• McMillan degree of G(s) = the dimension of a minimal realization of G(s).
• Poles of G(s) = roots of bi(s)
• transmission zeros of G(s) = the roots of ai(s)
z0Î C is a blocking zero of G(s) if G(z0) = 0.
