ABSTRACT:
Arrangement for reducing cross talk between electrical circuit conductors wherein the conductors lie within individual parallel channels within the same plane or different parallel planes within the induced voltage or cross talk region of an energized and a quiet conductor and either converge or diverge with respect to each other. The amount of relative convergence or divergence, preferably mor than six degrees and less than 15 degrees, is that required to attenuate the magnitude of any signal induced by the activated conductor in a neighboring or quiet conductor to maintain an acceptable and desired signal-to-noise ratio.
