Then, besides at most m - 1 even number counting multiplicities, real or complex conjugate zeros, the function [C.sub.[sigma]](z) - f(z) has only real zeros with the following distribution properties:
Then the eigenvalues of A are real or occur in complex conjugate pairs.
The use of a multi-harmonic load based on an arbitrarily width modulated transmission line [19] provides a precise control over the position of the pair of complex conjugate poles created after reaching the condition expressed by (2) [7].
An indication is given in Figure 2, based on the a priori knowledge that the real part of both complex conjugate roots is -0.5.
where [Q.sub.i] is the Q-factor of the i-th complex conjugate pole pair; n is the number of these pole pairs; [Q.sub.max] is specified Q-factor limit.
Assume that [lambda]E - A is stable and that the complex shift parameters appear in complex conjugate pairs {[[tau].sub.k], [[tau].sub.k+1] = [[bar.[tau]]].sub.k]}.

(this would not be the case if the [z.sub.i] were arbitrary instead of real or complex conjugate).
two-dimensional x-y plot of the quadratic equation does not reveal the location of the complex conjugate roots, and the interested student might well be forgiven for asking, "Where exactly are the roots located and why can't I see them?" In the author's experience, this sort of question is hardly ever raised--or answered satisfactorily--in school Years 11 or 12, or in undergraduate mathematics courses.
