Abstract
Techniques for obtaining a propagation delay through first and second transmission lines having substantially equal propagation delays may include: providing a first signal to the first transmission line; providing a second signal to the second transmission line; detecting an incident edge of the first signal on the first transmission line; detecting a reflected edge of the second signal on the second transmission line; and determining the propagation delay based on times of detection of the incident edge and detection of the reflected edge.
