Method and system for simulation of frequency response effeccts on a transmission line due to coupling to a second electrical network by direct synthesis of nulls

摘要

The present invention provides a method and system for simulating the effect on the frequency response of a transmission line due to the coupling of a second electrical network to the transmission line. It is observed that signals propagating through the second electrical network are reflected at the end of the second electrical network, thereby propagating back to the point of coupling with the transmission line causing partial cancellations of signals present. Thus, the second network effectively operates as a delay line, with an overall effect of creating nulls of various widths and depths in the frequency response of the transmission line. This second delay-line like network is replaced with a significantly simpler configuration.
