The paper presents an efficient computation sensitivity method for the analog two-port linear networks, without using the circuit topology. It is consider the steady state non-sinusoidal regime and the algorithm analyze the sensitivities of the network functions correlating it to the relative values which characterize the input current and voltage harmonics. Numerical examples are used for the discussion of some aspects related to the sensitivity groups' problems.

A new method for calculation of first order sensitivity and sensitivity groups for Multiple FeedBack (MFB) filter in non-sinusoidal regime is presented. Such a group of linear dependent parameters is defined the relative input values of current and voltage harmonics. The interdependence of the various network sensitivities for a given network needs special consideration. Numerical example for Butterworth low-pass filter is used for the discussion of some aspects related to the sensitivity groups' problems.

“…Consequently, the sums could be generalized for a broad class of physical systems. El-Turky and Khalaf [8] considered the sensitivities of numerator and denominator coefficients of a network function. Invariant sensitivity sums have been found and extended to include pole and zero resonance frequencies, and quality factor Q sensitivities.…”

SUMMARYIn this paper, a new class of invariant sensitivity sums of higher-order sensitivities is given. Sensitivity sums considered are relevant to a network function of general lumped time-invariant circuits containing passive and active elements. It is assumed that the circuit is linear and consists of one-port elements and two-port elements only. A part of the one-port elements is described by admittance parameters and the other part by impedance parameters. The rest of the one-port elements are independent sources. Two-port elements are only controlled sources. Hybrid matrix should describe functional relationships of the elements. Formulas for invariant sums of sensitivities of first, second, third, and fourth order are presented.
