The analysis of signal propagation in the time domain in two-conductor transmission lines (TLs) using an analytical approach is presented in the paper. New analytical models describing TEM-wave propagation in the time domain are developed. Transmission line analysis (modal analysis) was used to create the analytical models. The model is characterized by taking into account the asymmetry of the line cross-section and over-reflections from loads at both ends of the line. For the first time, an analytical condition allowing to equalize the amplitudes of the first two pulses at the output of a two-conductor asymmetric TL is presented. It is verified on an asymmetric line with broad-side coupling.It is obtained that the equalization of the pulse amplitudes leads to minimization of the maximum amplitude at the output of the transmission line. This is useful in the design of filters that operate on the principle of modal decomposition of the interference pulse.
