Abstract
Let H (z) be a rational transfer function with associated nonnegative impulse response sequence. The paper considers the question: When does there exist a triple A ε R NXA b ε R N c ε R N with all nonnegative entries and H(z) = c′(zI - A) -1b? An essentially complete characterization is given of the H(z') allowing such a realization in terms of the location of the pole or poles of H(z) with maximum modulus.
