Abstract

The advantages and limitations of time-domain pseudo-random binary sequence (PRBS) excitation methods for system identification of individual modes within a multi-conductor transmission system are discussed. We develop the modifications necessary to standard frequency-domain transmission-line models to match time-domain experimental data from several types of transmission systems. We show a variety of experimental results showing very good to excellent agreement with our model's predictions, up to approximately 10 GHz.
