Abstract

The convolution method is applied to analyse lossy multiconductor lines with non-linear loads. The line is described as a time-domain m-port, through the input and transfer impulse responses. A new method is used to evaluate analytically the principal parts of these responses, i.e., the parts containing all the irregular terms, such as Dirac pulses. Once the irregular parts are known, the regular remainders are easily calculated by numerical inversion. The convolution integrals have been evaluated using two different methods, one based on crude trapezoidal rule and the other based on a fast recursive algorithm. The latter is obtained by an exponential fitting of the regular parts of the impulse responses. A comparison between the computation times of these two methods is presented
