Signal transmission line performance parameters determining method, involves detecting reflected signal impulse portions at closed end, and determining performance parameter of line based on reflected signal impulse portion

摘要

The method involves forming a signal impulse, so that impulse corresponds to a signal impulse. The formed impulses are supplied at a closed end of a reference signal transmission line (36), which is frequency mismatched at a far end. The reflected signal impulse portions are detected at the closed end. Performance parameter of the line is determined based on the reflected signal impulse portion. An independent claim is also included for a pulse former with a time domain equalizer and a filter.
