Sensitivity analysis for timedomain response of nonuniform coupled transmission lines with nonlinear loads

Since the sensitivity of non-uniform coupled transmission lines is hard to analyse, a precise integrated way in time domain is put forward in this paper. The coupled transmission lines equation of telegrapher in time domain is discretized as well as differenced in spatial domain by the means. Non-uniform couple transmission lines sensitivity's first order is established. Thus the analysis of timedomain response' sensitivity becomes to solve the differential first-order equation. The paper's approach could be used in all kinds of non-uniform and uniform transmission loads and lines. Computed results indicate that the proposed method is reliability and validity.
