Abstract
In some embodiments, a first conducting line, having a characteristic impedance, connects to a digital device while a second conducting line, also having a characteristic impedance, connects to another digital device. An impedance pathway connects the two conducting lines and has an impedance of at least one-third of the first conducting line's characteristic impedance and of at least one-third of the second conducting line's characteristic impedances. Other embodiments are claimed.
