This paper establishes a link between the Lagrange's continued fraction expansion (CFE) and two CFEs the author recently introduced for approximating the operators , and their discrete realizations. The zeros and poles of these new approximations alternate on the negative real half-axis of the s-plane (in the case of analog realizations) and on the real segment inside the unit circle of the z-plane (in the case of discrete realizations). Finally, the paper shows that the discrete approximations of s

have poles and zeros enjoying a nice symmetrical distribution on the z-plane. |
