he driving point properties of a ladder type distributed RC network, characterized by the distributions

and

, are investigated. It is shown that the infinite length network exhibits, at one of the ports, a constant argument impedance of the form

, in an asymptotic manner. With a finite length, the approximation is found to be valid over a finite frequency band only, while the asymptotic behavior is that of an impedance

, irrespective of the values of

and
