1. A method for determining mutual coupling between adjacent communication transmission lines, the method comprising:
providing a first periodic signal to a first communication transmit end of a first communication transmission line;
providing a second periodic signal to a second communication transmit end of a second communication transmission line, wherein the first communication transmission line is adjacent to the second communication transmission line;
measuring a time of zero-crossing at a second communication receive end of the second communication transmission line compared with a zero-crossing of an ideal reference signal; and
determining a mutual coupling level based on the time of zero-crossing on the second communication transmission line compared with the zero-crossing of the ideal reference signal that was measured.
