Abstract

An important consequence of the passivity of a network driving-point impedance, Z(s), is that knowledge of its resistive part along the imaginary axis of the complex - frequency plane (s = α + jω plane) suffices for the determination of Z(s) everywhere on the complex plane. By exploiting this property we show that a passive rational function fit of the driving-point impedance of a passive network, valid over a desirable frequency bandwidth, 0 ≤ ω ≤ ω_BW, can be readily obtained from the sampled values of its real part over a range of frequencies 0 ≤ ω ≤ ω_s where ω_BW ≤ ω_s. The fitting algorithm proposed for this purpose is computationally simpler than related, commonly used, rational fitting processes.
